The size of the planet earth is quite large compared to the size of the moon that is one-quarter the diameter of the earth. A large body which directly orbits any star (or star cluster) but which has not attained nuclear fusion. According to modern understanding there are 8 planets in the solar system, with Uranus and Neptune being the last two. The size of the stars is comparatively larger than the planets. The moon of earth, for example, is a part of our solar system. Technically, the moon also orbits the Sun as it spins around its planet, but because it has its own sub-orbit of a planet scientists define it as a moon. around the world. The International Astronomical Union (IAU) defines a dwarf planet as a celestial body in direct orbit of the Sun that is massive enough for its shape to be controlled by gravitation, but that unlike a planet has not cleared its orbital region of other objects.
