SOLAR SYSTEM
========================================================
Our little corner of the Universe is called the solar system.
The solar system consists of the Sun and its eight main planets, their satellites, asteroids, comets, meteors and other dwarf planets. The Sun is at the one of the two “centers” of the Solar system and the planets revolving around it in elliptical orbits. Let us take a look at some quick facts about the Solar System:
The closest planet to Sun is Mercury and the farthest is Neptune.
Pluto is a dwarf planet – relegated from its status as the ninth planet.
The eight planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
You can remember the order using the mnemonic: My Very Energetic Mother Just Showed Us Night-sky.
The Solar System is the Sun and all the objects that orbit around it. The Sun is orbited by planets, asteroids, comets and other things. The Solar System is about 4.6 billion years old.The other objects are pulled into orbit around the Sun. The Sun is mostly made out of hydrogen, and some helium.
