The asteroid strike would have "completely removed the original surface" of Ganymede, thanks to the crater reaching a whopping 25 percent of the moon's size, the researcher said in a recent statement.
How many moons does Jupiter have? Scientists have discovered dozens of them, but the answer may be more complicated than it seems.
