Definition: A planet is a celestial body that orbits around a star, with sufficient mass to assume hydrostatic equilibrium (a spherical shape), and cleared of sufficient mass to support its own gravity.
Characteristics:
**Size:**Planets range in size from the smallest, like Mercury, to the largest, like Jupiter.
**Distance from the Sun:**The Sun is the center of the Solar System, and planets orbit around it.
**Composition:**Planets can be made of various materials, including rocky, metallic, and gas giants.
**Orbit:**Planets have different orbital periods, meaning they take different amounts of time to complete their orbits around the Sun.
**Atmosphere:**A planet's atmosphere is a mixture of gases that surround the planet.
**Gravity:**The gravitational force of a planet attracts its objects, including other planets, moons, and asteroids.
**Life:**The potential for life on planets has been extensively studied.
**Origin:**The origin of planets and life in the Solar System is still a mystery.
Examples:
Mercury: The smallest planet, composed mainly of rock and dust, with a very hot surface.
Venus: The hottest planet in the Solar System, with a thick atmosphere composed mostly of carbon dioxide.
Earth: Our home planet, with a diverse atmosphere and water oceans.
Jupiter: The largest planet, known as the "planet with a million faces," with a massive atmosphere and a great variety of moons.
Saturn: Another giant planet with a complex atmosphere and a beautiful ring system
