SOLAR SYSTEM
1. Solar System
The Solar System is a vast collection of celestial bodies bound together by the gravitational force of the Sun. It consists of the Sun, eight planets, their satellites, asteroids, comets, meteors, and interplanetary dust and gas. It was formed about 4.6 billion years ago from a giant cloud of gas and dust called the solar nebula. The Sun is located at the center and contains about 99.86% of the total mass of the Solar System. The planets revolve around the Sun in elliptical orbits. The Solar System provides valuable insights into the origin, evolution, and structure of the universe.
2. Order of Planets from the Sun
The eight planets of the Solar System are arranged according to their distance from the Sun. Their order is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is the closest planet to the Sun, while Neptune is the farthest. The first four planets are terrestrial or rocky planets, and the outer four are giant gaseous planets. This arrangement helps scientists understand planetary formation and characteristics. Each planet has unique features, atmospheres, and orbital periods. Remembering the sequence is important in astronomy and competitive examinations related to science and geography.
