The determination of habitability may depend on many factors, such as amount of water, eccentricity, presence of any moons, magnetic field, distance from its star, atmosphere, composition, etc. Here, we focus on two: temperature and size, and determine the fraction of stars that have planets ...
Four ofJupiter's moons: Io, Europa, Ganymede and Callisto — known as the Galilean moons — were the first celestial objects to be discovered orbiting an object other thanthe sunorEarthwhenGalileo Galileifirst observed them in 1610. Most of Jupiter's moons are small, with about 60 of the ...
