🌔Galilean Moons🌖
The Galilean moons are the four biggest of Jupiter's moons. They were discovered by Galileo, centuries before astronomers identified the others, smaller ones.
Ganymede is the biggest of Galilean moons. At 5262 km across, it is larger than the planet Mercury.
Ganymede looks solid, but under its shell of ice is 900 km of slushy ice and water.
At 4806 km across, Callisto is the second biggest moon of Jupiter.
Callisto is scarred with craters from bombardment early in the Solar System's life.
Io is the third largest moon at 3642 km across.
The surface of Io is a mass of volcanoes caused by it being stretched and squeezed by Jupiter's massive gravity.
Io's yellow glow comes from sulphur, which is thrown out as far as 300 km upwards by the moon's volcanoes.
The smallest of the Galilean moons is Europa at 3138 km across.
Europa has a smooth icy surface full of cracks, but the Galileo probe discovered an ocean of water under the ice where there might be living creatures.

Sedna is an icy solar system body that is so distant, it takes 11,400 years to orbit the sun. It resides roughly 3 times further out from the sun than Neptune, and is two third the size of Pluto. It is one of the most distant objects known in the solar system, and although Sedna is covered in an ice, it appears almost as red as Mars.
