The Solar System consists of planets, dwarf planets, asteroids, comets, and meteors orbiting the sun. Gravity governs the elliptical orbits of planets as proposed by Copernicus. Ancient astronomy viewed Earth at the center of a celestial sphere with constellations.
The Solar System consists of the sun, eight large planets, dwarf planets like Pluto, asteroid belt, comets, and meteors. The planets and other objects orbit the sun in elliptical paths in the same direction and nearly on a common plane.
Gravity and Orbits: The force of gravity holds planets in elliptical orbits around the sun, as proposed by Copernicus. The solar system formed from a giant gas and dust cloud about 4.6 billion years ago, explaining the planets' alignment and orbits.
Celestial Sphere: Ancient observers believed in a geocentric model with Earth at the center of a star-studded celestial sphere. The Sun's path on the celestial sphere is the ecliptic, and the celestial sphere is divided into 88 constellations.
