Planets are celestial bodies that orbit stars. In our Solar System, there are eight planets, including Earth, Mars, and Jupiter. They are divided into terrestrial (rocky) planets and gas giants.
Galaxies are massive systems of stars, dust, and gas bound together by gravity. The Milky Way is our home galaxy, and it contains billions of stars and solar systems.
Black holes are regions of space with intense gravity, where nothing can escape, not even light. They are formed from the remnants of massive stars after they collapse.
Stars are glowing balls of gas that produce light and heat through nuclear fusion. They are born in nebulae and can live for billions of years.
