Bodies in Space
Bodies in space include stars, planets, moons, asteroids, comets, and other celestial objects. They exist in a vast, mostly empty universe governed by gravity, which keeps planets orbiting stars and moons orbiting planets. Stars are massive, luminous spheres of hot gases that produce light and heat through nuclear fusion. Planets are large objects that orbit stars, shaped by their gravity and composition. Moons are smaller bodies orbiting planets. Together, these bodies form a dynamic, interconnected cosmos, showcasing the diversity and complexity of our universe.
