Hubble spots something very, very strange hurtling through our solar system
The Hubble space telescope has unravelled the mystery of a strange asteroid which had also been classified as a comet - and which had puzzled astronomers.
Hubble was used to image the asteroid, designated 2006 VW139, in September 2016 - and the image revealed that it's not one, but two asteroids.
The two rocks are orbiting each other at a distance of 60 miles - and behave very weirdly, the researchers say.
