NASA lists 820m asteroid nearly as big as world’s tallest building Burj Khalifa

NASA is tracking a massive asteroid almost as big as the world's tallest building that is set to hurtle past Earth next month.

Asteroid 2000 WO107 is set to speed past our planet on November 29 and is one of the largest and fastest asteroids to skim past Earth in 2020.

NASA's NEO Earth Close Approaches list estimates 2000 WO107 as being between 370m and 820m in diameter.

By comparison, the world's tallest building, the Burj Khalifa, stands 829.8m tall.

The space agency also says the massive rock will zoom past earth at an astonishing 25.07 kilometres per second – equivalent to 56,079.993mph.

The asteroid will pass the planet at 11.19 times the Earth-moon distance – making it close enough to be monitored by the US space agency, but posing an extremely low risk of causing any damage.

Experts observing the asteroid's trajectory say it will come closer to Earth on December 1, 2040, when it will be 242,000km from the planet.

This will put the massive asteroid closer to Earth than the moon, which is 384,400km away.

It comes as space rock 2020 RK2, an asteroid which is bigger than a Boeing-747 jet, collided with Earth’s orbit on Wednesday, October 7.

The asteroid was first spotted by astrologists last month.

It is classed as an Apollo asteroid, which is an asteroid that will cross the Earth’s orbit as it safely flies past.

Asteroid 2020 RK2 is hurtling through space at a speed of 6.68 kilometres per second, which is the equivalent to 14,942 miles per hour.

A 200 metre-wide asteroid labelled 2020 PM7 also sped past Earth on September 29 at a speed of eight kilometres a second, equivalent to 17,895mph.
