Asteroid from out of this solar system spotted hurtling past Earth, A/2017 U1 is discovered!

It's over 1,600 times laster than Usain bolt!

It’s really rare that we get any visitors from outside the solar system!

We’ve never seen aliens or any UFOs but some astronomers believe they have spotted something that’s sort-of alien…

A/2017 U1 is an asteroid that’s from a completely different solar system.

It is only 400 metres across but it’s moving incredibly fast at more than 20,000 metres per second! That’s 1,600 times faster than Usain Bolt!

The asteroid began a close approach to the sun in September, then swung around and passed within 15 million miles of Earth on October 14th.

Problem is, we didn’t spot it until four days later on October 19th, when it was already heading away from us!

Luckily, astronomers around the world pointed their telescopes to the asteroid, so we have lots of photos and data of it…
