Asteroid the Size of the Great Pyramid of Giza Set to Pass Earth Tomorrow

An asteroid that could be almost 600 feet wide is set to fly by Earth on Saturday, passing us at a speed of more than 29,000 miles per hour.

The asteroid, named 2020 TY1, was first discovered in October. It is expected to pass at a distance of around 3.5 million miles, which is about 14 times the distance between Earth and the moon, meaning it poses no risk to our planet.

It is one of the largest asteroids to pass Earth in recent weeks, with the last of a similar size passing by on October 22. The space rock is estimated to be between 260 and 590 feet wide, making it around the size of the Great Pyramid of Giza, which is 455 feet tall.

Despite passing Earth by millions of miles, 2020 TY1 is considered a near Earth object (NEO). NASA tracks the orbits of these objects to support the agency's planetary defense office. This initiative allows NASA to detect and track potentially hazardous objects—defined as anything that comes within five million miles of Earth—that measures more than 100 feet in width. An object of this size or larger has the potential to cause significant damage on Earth, NASA says.

On November 2, an asteroid came incredibly close to Earth in astronomical terms, passing us by at a distance of around 4,000 miles. Before it's close approach, astronomer Neil deGrasse Tyson said the asteroid, 2018 VP1, would "buzz cut" Earth. "It's not big enough to cause harm," he wrote. "So if the World ends in 2020, it won't be the fault of the Universe."

This asteroid, which measured up to 12 foot in width, was the closest to pass Earth in the past 12 months, according to data from NASA's Center for Near Earth Object Studies (CNEOS).

Another asteroid is also set to fly by Earth on Saturday, with the object called 2019 XS passing us at a distance of around 3.4 million miles. This object is estimated to be up to 280 feet wide.

At the end of the month, an enormous asteroid is set to make its close approach. The object, named 2000 WO107, is up to 2,690 feet wide. It will zoom past Earth on 29 November—exactly 20 years since it was first discovered. 2000 WO107 is expected to pass at a minimum distance of 2.7 million miles, traveling at a speed of around 56,000 miles per hour.
