NASA is watching a huge space rock that's over a mile wide and it's about to make a close approach to Earth.

Asteroid 7335 (1989 JA) is firmly on Nasa's table and stands out as one of the largest space rocks on the list.

The US space agency estimates that the mega asteroid is just over 5905 feet wide.

That means it's over 1.1 miles across.

In comparison, New York's iconic Empire State Building stands at 1,454 feet tall.

An asteroid of this size would cause some serious damage if it hit Earth.

Fortunately for us earthlings, Asteroid 7335 (1989 JA) is expected to pass us from around 2.5million miles away.
