Known as flow formations, these channels could be etched on bodies that would seem inhospitable to liquid because they are exposed to the extreme vacuum conditions of space. Pocked with craters ...

Most of them have a diameter of between 20 to 100 kilometres, a few up to 500 kilometres, but none are larger than Ceres: with its 1000- kilometre diameter, it makes up more than a third of the total ...

The asteroid belt is not the only repository of these space ... Asteroids are known to range in size from around 329 miles in diameter (i.e. Vesta, which accounts for 9 percent of the total ...
