Introduction to the Solar System

The solar system is a gravitationally bound system consisting of the sun and the objects that orbit it. It includes eight planets, numerous moons, asteroids, and comets. The primary star and source of energy is the sun, which accounts for the vast majority of the system's total mass.

Planetary Composition and Characteristics

The inner planets—Mercury, Venus, Earth, and Mars—are primarily composed of rock and metal, making them terrestrial worlds. In contrast, the outer planets—Jupiter, Saturn, Uranus, and Neptune—are gas giants or ice giants, possessing massive atmospheres dominated by hydrogen and helium.

Formation and Dynamics

The solar system formed approximately 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. This process led to the formation of a protoplanetary disk. Over millions of years, gravity caused dust and debris to clump together, eventually accreting into the celestial bodies we observe today.
