Orion star cluster only 15% of stars in the galaxy host planetary systems and one of those stars is our own Sun revolving around the Sun are eight planets the planets are divided into two categories based on their composition terrestrial and Jovian terrestrial planets including Mercury Venus Earth and Mars are primarily made of rocky material their surfaces are solid they don't have ring systems they have very few or no moons and they are relatively small the smallest and closest to the Sun is mercury which has the shortest orbit in the solar system at about 3 earth months. Venus is the hottest planet with temperatures of up to 867 deg
