Mystery Object to whiz close to earth

A mystery object from space is to whiz close by Earth today.

It will not hit the planet, but scientists are stumped by what exactly it is.

Astronomers say it might be space junk or it could be a tiny asteroid, too small to cause damage even if it hit.

It is 10 to 15 metres wide at most.

It would streak by earth today at 5.17 pm (Indian Standard Time)
