Our solar system’s biggest planet has some very small moons.
A team of astronomers has reported the discovery of a dozen new moons circling Jupiter.
That brings the number of moons in orbit around Jupiter to 79, the most of any planet.
The ringed-planet Saturn is next with 61.
The scientists say the moons weren’t observed before because they are quite tiny – for moons – and the biggest ones only about three kilometres across.
