Asteroid bigger than a bus will shoot by closer than the Moon THIS WEEK

PY2 belongs to a class of bodies racing around the system dubbed by astronomers near-Earth objects or NEOs.

NEOs are all comets and asteroids that come within 0.05 astronomical units (au) of our planet – 4,647,790.4 miles.

And although the distance might seem inconsequential, in astronomical terms, it is a very close encounter.

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.”
