The earth will not get one, but two visitors from the room this weekend.
Astronomers expect an asteroid known as 1999 KW4 to oscillate at Earth at 7:05 p.m. ET on Saturday – and when it does, it will bring its own moon.
"It is one of the closest binary airbags probably in recent history," says planet scientist Vishnu Reddy NBC News . "That's what makes it a very interesting goal."
Asteroid 1999 KW4 is 1.5 kilometers (.93 miles) wide. It is about three times the size of its moon, which bells into a width of approx. 0.5 kilometers (.3 miles).
Even in their vicinity, the space rocks are still more than 3 million miles away, so don & # 39; Don't worry about those who are smashing into the ground. In fact, they won't even get close enough to see with the naked eye.
However, the couple will not be so close to Earth until 2036, so if you want a glimpse of the dynamic duo, be sure to get your telescope ready on Saturday night.
