NASA have released an image of Ultima Thule with two space rocks looking like a snowman.
The high-resolution images, taken by the New Horizon spacecraft, show a 21-mile tall snowman-shaped object, which is a billion miles beyond Pluto.
The dark object is formed of two spheres which have combined to form one celestial object.
Alan Stern, principal investigator for New Horizons, said: "It is only really the size of something like Washington DC and it is about as reflective as garden variety dirt.
"It's a snowman if it's anything at all.
