Heaviest Things on Earth

Heaviest Things on Earth: The Top 10 Weighty Wonders

Greetings, curious minds! In today’s article, we’ll dive into the world of the heaviest things on Earth, the mightiest and most jaw-dropping of all man-made objects.

I’ve done my homework and rounded up the top 10 heaviest objects in the world, all listed under several categories. These objects will surely blow your mind (and break your scale).

Obviously, I didn’t place objects weighing billions of pounds on my bathroom scale. I doubt they’ll fit.

Instead, I’ve compiled a list based on information from sources such as the Guinness World Records, the National Institute of Standards and Technology (NIST), and other science and engineering sources.

In addition, it is quite difficult for our brains to perceive enormous numbers accurately. That’s why I’ve made sure to provide some very practical comparisons and brief facts to help you better grasp the weight of each object.

Top 10 Heaviest Objects in The world

Before getting into the specifics of each object, it is worth noting that due to the logistical difficulty of measuring the weight and mass of such objects, their weight totals are estimates sourced from the data available at the time of making this list.

So, without further ado, let’s start with the least heavy object on our list.

Washington Monument Washington DC 1622 million pounds

Washington Monument (Washington, DC); 162.2 million pounds

The Washington Monument is one impressive stone structure located on the National Mall in Washington, D.C., and attracts over 500,000 visitors every year.

It stands tall at 555 feet (169 meters) and weighs a massive 90,854 tons (82,506 metric tons). Despite its massive weight, the Washington Monument still falls short of being the heaviest man-made object in the world.

However, that 162 million pounds make it the heaviest in the USA. To put its weight in perspective, 162.2 million pounds equals 12,135 African elephants!

Moreover, The Washington Monument s made of over 30 thousand granite blocks. You could build 30 average-sized houses with just one of those blocks!

Submerged communications cable under oceans 1764 million pounds

Submerged communications cable (under oceans); 176.4 million pounds

Ahoy matey! You might be surprised to see this one on this list. These cables are laid on the ocean floor and transmit data across the world’s oceans.

Some of which have provided electricity for communications since the 1860s. And the heaviest of them all weighs a whopping 176.4 million pounds!

Think about 176.4 million pounds another way. The largest animal in history is a blue whale, clocked in at 199 tonnes (or 438,719.5 pounds.).

To match the heaviest Submerged communications cable out there, it would take around 510 blue whales. Yup, that’s almost 3% of all the remaining blue whales worldwide.

Another interesting aspect is that these cables can stretch thousands and thousands of miles long, even longer than the distance from New York to Australia!

For example, in 2017, AT&T operated nearly 90 undersea cable systems, stretching more than 438,000 miles in total, which as a whole would be plenty to circle the Earth’s equator over 17 times.

The freight train Western Australia 1995 million pounds

The freight train (Western Australia); 199.5 million pounds

Next on our list is a 20-year-old freight train in Western Australia. Being the heaviest freight train ever and the longest at 4.5 miles long and 199.5 million pounds.

To put that weight in perspective. The General Sherman Tree, also known as the giant sequoia tree, is the heaviest living thing in Earth’s history and the largest living organism (by volume) on the planet.

These redwoods of almost unimaginable size can reach 311 feet tall and weigh up to 6000 tons or 12 million pounds. Even still, you would need around 16 and a half Giant Sequoias to match the weight of this one extra Large freight train.

Nimitz Class aircraft carrier various 204 million pounds

Nimitz Class aircraft carrier (various); 204 million pounds

Nimitz-class aircraft carriers are the largest Warcrafts ever to be built. Of these, ten were built between 1975 and 2009. Each weighs about 204 million pounds. And you can bet that colossal mass held entire airports’ worth of aircraft at a time.

Let’s look at 204 million pounds from a different angle. According to a study by the University of Idaho, the average NFL player weighs 245.86 pounds.

Accounting for 32 teams with 53 players on each roster, that’s 1696 players winning the grand total of 416,978 pounds. You would need 489 National Football League’s worth of players to equal the weight of one single Nimitz carrier.

SSCV Sleipnir crane vessel 602 million pounds

SSCV Sleipnir crane vessel; 602 million pounds

The SSCV Sleipnir crane weighs a mind-boggling 273,000 tonnes (Fully loaded)! This vessel is a marvel of engineering, and it’s amazing to think about how much weight it can lift and move around with ease.

The Sleipnir is truly a beast of the sea, with two revolving cranes, each capable of lifting a whopping 10,000 tonnes! It’s no wonder that this vessel is the largest crane vessel in the world, with its eight columns and streamlined pontoons designed to reduce drag and provide calmer motions under higher sea states.

So what exactly are 273 tons? We all know about the Titanic, right? That’s the ship that sunk after hitting an iceberg back in 1912. Well, the Sleipnir makes the Titanic look like a bath toy.

The Titanic weighed around 52,000 metric tons, which is less than a fifth of the Sleipnir’s weight. That’s like comparing a minivan to a monster truck.

Palace of the Parliament Bucharest Romania 16 billion pounds

Palace of the Parliament (Bucharest, Romania); 1.6 billion pounds

Moving on, we have the Palace of the Parliament in Bucharest, Romania. In the 1980s, Nicolae Ceausescu ordered the palace built.

However, he never witnessed the project’s completion since the citizen uprising saw him executed in 1989, five years before the palace’s completion.

The Palace of the Parliament is the heaviest building on Earth at a ridiculous 1.6 billion pounds. It is also the second-largest administrative building in the world after the Pentagon.

Gullfaks C installation oil storage facility North Sea 3 billion pounds

Gullfaks C installation oil storage facility (North Sea); 3 billion pounds

First installed back in on 4 November 1989 and got to pumping one year later. The Gullfaks C installation oil storage facility stationed in the North Sea around Norway is the heaviest movable manmade object in history.

This mammoth facility produces over 250,000 barrels of oil daily, so it makes sense that it weighs 3 billion pounds (or 1,500,000 tons). Yup, that’s more pounds than you can count on your fingers and toes combined!

So what exactly are 3 billion pounds? Well, Both the Gullfaks C and the famous Statue of Liberty are seen as massive, man-made objects that would make you go “woah” when you see them.

However, you’d need about 6,000 clones of the status of liberty to match the weight of the Gullfaks C.

Great Pyramid of Khufu Egypt 12 billion pounds

Great Pyramid of Khufu (Egypt); 12 billion pounds

The Great Pyramid of Khufu, also known as the Pyramid of Giza, is a true world wonder.

While not exactly the largest pyramid in the world (The pyramid of Cholula took that spot), it is still the largest of Egypt’s pyramids and the oldest of the Seven Wonders of the World.

It comprises 2.3 million stone blocks, each weighing about two and a half tonnes. Do the math, and that’s a whopping 12 billion pounds (or 5,750,000 tons). Imagine it this way: This thing is so massive it makes Godzilla look like a little gecko.

What better way to compare the Pyramid of Khufu suite with that of another world wonder, the Eiffel Tower? This iconic structure may not be as old as the Khufu Pyramid, but it’s still a heavyweight champ in its own right.

However, regarding weight, it’s like comparing a feather to a bowling ball. In fact, it would take about 600 Eiffel Towers to match the weight of the Khufu Pyramid. That’s a whole lot of metal!

Three Gorges Dam China 208 billion pounds

Three Gorges Dam (China); 20.8 billion pounds

Besides being a true engineering marvel, The Three Gorges Dam in China is also the second heaviest man-made object on Earth, weighing an astonishing 20.82 billion pounds (or 10.42 million tons).

In terms of installed capacity, it’s the world’s largest power station, generating over 22,500 megawatts of electricity! This massive dam is approximately 1.4 miles (2.3 km) long and 607 feet (185 meters) high, taller than the Statue of Liberty.

In fact, this dam is so huge that scientists believe it could actually slow the Earth’s rotation if it ever blocked its maximum amount of water, making each day 0.06 microseconds longer.

How massive could 20.82 billion pounds be? You might wonder. Well, the largest known elephant in history was a 24,000-pound elephant male from Angola. To equal the massiveness of the Three Gorges Dam, you would need 867,500 Giant Angolan elephants.

Also, remember the Nimitz-class aircraft carriers we mentioned earlier? If you could get your hands on about 123 fully loaded warcraft of those, that would do the trick.

The Great Wall of China 116 billion pounds

The Great Wall of China; 116 billion pounds

This might shock some, but No man-made object in history is heavier than the Great Wall of China. In fact, it’s not even close. Being 13,000 miles long also makes it the longest wall in the world.

While you can’t actually see it from space, this wall has enough bragging rights to last the rest of civilization. With an inconceivable 116 billion pounds, it has more than left its mark on both history and the planet.

Think about 116 billion pounds another way. The largest animal in history is a blue whale, clocked in at 173 tonnes or 346,000 pounds to match the Great Wall of China; you would have to clone that particular Blue Whale 335,260 times. Sadly, only about 25,000 (at best) blue whales are left in the world today.

Honorable Mentions

Below is another set of objects that didn’t quite make it to our list of the heaviest things on Earth. However, they are surely worthy of at least being mentioned. While you can’t actually see it from space, you can bet

The Boeing 747-8:

The jumbo jet of the skies! This massive plane is the largest commercial aircraft currently in production, with a maximum takeoff weight of around 975,000 pounds (442,253 kg). And it can carry up to 660 passengers – that’s like a small village traveling through the air.

The Large Hadron Collider (Switzerland/France)

the world’s largest and most powerful particle accelerator is located at CERN, near Geneva, Switzerland. With a circumference of approximately 17 miles (27 km), it’s larger than the island of Manhattan in New York City. The LHC weighs approximately 38,000 tons (83.7 million pounds), which is roughly the same weight as yo mama.

The ITER Tokamak (France)

Currently under construction, The ITER Tokamak in France is a giant fusion reactor designed to replicate the process that powers the sun and other stars.

This massive machine weighs in at a staggering 23,000 tons (50.7 million pounds), roughly equivalent to 3,176 average-sized cars. It’s a behemoth of a machine, with a diameter of over 100 feet and complex components that are being assembled by a team of international experts.

The Burj Khalifa (Dubai):

The Burj Khalifa is a skyscraper located in Dubai, United Arab Emirates, and it’s the tallest building in the world. Standing at the height of approximately 2,717 feet (828 m), it’s over twice as tall as the Eiffel Tower.

Burj Khalifa weighs approximately 500,000 tons (1.1 billion pounds), which is equivalent to the weight of about 100,000 elephants.

To put that into perspective, it’s equivalent to the weight of 6 USS Gerald R. Ford aircraft carriers or 1,818 blue whales.

The Statue of Unity (India):

The Statue of Unity, a towering bronze effigy of Sardar Vallabhbhai Patel, an Indian statesman and a revered champion of independence, is a testament to the sheer human capacity for monumental achievement.

This imposing structure stands an impressive 597 feet high (equivalent to 182 meters) and weighs an astounding 1.6 billion pounds (roughly 730,000 kilograms), an amount equivalent to the weight of 2,186 elephants!

The statue is an engineering masterpiece, comprising 1,700 tonnes of bronze and 1,850 tonnes of bronze cladding, and was crafted by over 3,000 diligent workers who worked for a grueling 56 months to bring this marvel to life. Undoubtedly, the Statue of Unity is a true representation of human ingenuity and creativity.


Some of the heaviest objects in the world are truly jaw-dropping, ranging from the Washington Monument to the SSCV Sleipnir crane vessel.

As mentioned before, I’ve selected these objects based on information from credible sources such as the Guinness World Records and the National Institute of Standards and Technology.

Also made sure to provide practical comparisons and brief facts, this list provides a glimpse into the logistics and engineering feats required to create and move such massive objects.
