An asteroid almost a kilometer wide with its own moon passes over the Earth this weekend

An asteroid nearly 1.5 km wide and with its own moon is planned to pass to the Earth on weekends.

Together, the two space rocks are known as the binary asteroid system, which means two asteroids that revolve around each other. The binary asteroid, called 1999 KW4 by NASA, will be about 3 million kilometers from the Earth, at its closest point, around 7:05 pm. HE Saturday, reports NBC News.

Although some outlets have noted that the asteroid, discovered in 1999, was classified as "potentially dangerous," scientists point out that there is absolutely no danger that it will strike the Earth.

The largest body in the pair, which is nearly a kilometer wide, has a broad ridge around its equator that makes it look like a spinning top, according to CBS News. The smallest rock is about a third of the size of his companion.

Arizona University planetary scientist Vishnu Reddy told NBC that the asteroid system would be "one of the closest binary flybys probably in recent history," but that it would still be too far away to be visible to the naked eye.

1999 KW4 will overtake the Earth again in 2036, notes LiveScience. It will still be too far away to pose a collision risk.
