390m asteroid set to flyby Earth safely at speeds of 53,000mph

New Delhi : A huge size rock, named Asteroid 2012 XA133, is all set to flyby Earth safely at an approximate speed of 53,000mph tomorrow. It has been on NASA's radar since 2012 at the Centre for Near Earth Object Studies (CNEOS) in California.

While there were scares among people that it may hit the planet Earth after NASA calling it "Earth close approach", the word close was in reference to astronomical terms which means it will be millions of miles away from the planet.

NASA said: "As they orbit the Sun, NEOs can occasionally approach close to Earth.

"Note that a 'close' passage astronomically can be very far away in human terms: millions or even tens of millions of kilometres."

On March 27, the rock will zip by from a distance of about 0.04453 astronomical units.

A single astronomical unit describes the distance from our planet to the Sun - about 93 million miles (149.6 million km).

Asteroid XA133 will cut this down to about 4.1 million miles (6.66 million km).
