This document provides an overview of the solar system, including its origin, components, and current state of study. It describes the sun and planets Mercury through Neptune. It also discusses dwarf planets, satellites or moons, asteroids, and comets. The solar system formed from a solar nebula according to the nebular hypothesis. Today, the solar system is studied using land and space-based telescopes as well as space missions.
