Today, January 18, a massive space rock, larger than any skyscraper on Earth, is projected to travel past the earth. The National Aeronautics and Space Administration (NASA) stated that the 1994 PC 1, also known as asteroid 7482, is projected to pass by Earth safely at a distance of 1,230,000 miles.

According to reports, NASA has classed asteroid 1994 PC 1 as 'possibly hazardous' due to its proximity to Earth while passing by. NASA's planet security experts have been studying the asteroid for decades.

According to Hindustan Times, the massive space rock is around 1.6 kilometers broad, making it twice the size of the world's tallest building, the Burj Khalifa (828 metres). This large asteroid has the potential to wreak catastrophic devastation to the Earth.

Asteroids that are over 140 meters in diameter and have orbits as close as 4.6 million miles from Earth's orbit around the Sun are classified as potentially hazardous by NASA.

Here's where you can keep track on asteroid 1994 PC 1.

NASA has been monitoring asteroid 1994 PC 1 for decades, and it is classified as a Near-Earth Object (NEO) since it is closer than 1.3 astronomical units (AU), which is equal to 93 million miles.

The closest approach of asteroid 1994 PC 1 to Earth, however, will take place today at 4.51 p.m. EST (3.21am IST on January 19). According to Earthsky, this will be the closest approach for at least the next 200 years for this massive space rock.

The most recent space rock to collide with the planet detonated in the atmosphere near Russia eight years ago.

A mission to deliberately crash a spaceship into an asteroid as a test run to avoid a big space rock from killing life on Earth was just launched by the American space agency. The spacecraft is projected to collide with the asteroid in the fall of 2022.
