An exoplanet is a planet that exists outside our solar system, orbiting a star other than the Sun. They vary in size, composition, and distance, from rocky ones like Earth to gas giants like Jupiter 🪐.

A star is a massive and luminous sphere of hot gas, primarily hydrogen and helium, held together by its own gravity. Nuclear fusion occurs in its core, releasing energy in the form of light and heat ☀️.

A constellation is a group of stars that form a recognizable pattern in the night sky. Historically, constellations have been used for navigation and storytelling 🌌.
