Heavenly bodies refer to natural objects in space, including stars, planets, moons, asteroids, and comets. These celestial entities are part of the universe and can be observed from Earth. Each type of heavenly body has unique characteristics, such as size, composition, and orbit. The study of heavenly bodies is a key aspect of astronomy, which explores their formation, movement, and interactions. For example, the Sun is a star that provides light and heat to Earth, while Jupiter is the largest planet in our solar system, known for its many moons and prominent storms.
