## TL;DR

The solar system contains the Sun, eight planets, dwarf planets, moons, asteroids, and comets. This repair maps astronomy claims to NASA and IAU sources.

## Core Explanation

The previous entry had weak coverage and too many broad sources. This version keeps three source-backed facts about the Sun-centered system, planets, and dwarf-planet definition.
