Advances in technology have lead to the discovery of new planets outside of our Solar System, and now even new moons in our own backyard. Two of them – the smallest ever discovered – were found orbiting Jupiter. That brings the number of Jovian moons to a whopping 66. The moons – each about 1 km in size – are very distant from Jupiter. It takes the tiny satellites 580 and 726 days to orbit the gas giant.
