The solar is made up of the sun, moon and eight planets. The names are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These names are written in order from first to last. Once there were nine planets. The ninth was Pluto which was known as the dwarf planet but now it has been excluded from the solar system. All the planets orbit the sun. The Sun has a temperature, at its core, of more than 28,080,000° F (15,600,000° C). Our planet is the Earth. The closer the planets are to Sun, the hotter they are. Four planets – Jupiter through Neptune – have ring systems, and all but Mercury and Venus have one or more moons.
