Planet

A planet is a large celestial body that orbits a star, such as the Sun. Our solar system contains eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Each planet has unique characteristics, including different sizes, temperatures, atmospheres, and surfaces. Some planets are rocky, while others are gas or ice giants. Studying planets helps scientists understand how solar systems form and whether life might exist beyond Earth.The planets travel around the Sun in paths called orbits, and each one takes a different amount of time to complete its journey. Mercury is the closest planet to the Sun, while Neptune is the farthest. Earth is the only planet currently known to support life because it has liquid water, a suitable atmosphere, and temperatures that allow living organisms to survive. Scientists use telescopes and space missions to explore planets and discover more about their environments.
