• The Sun: A star at the center, containing 99.86% of the system's known mass and dominating the system gravitationally.
• Planets: Eight planets orbit the Sun:
  • Inner, terrestrial planets: Mercury, Venus, Earth, and Mars.
  • Outer, gas giants: Jupiter, Saturn, Uranus, and Neptune.
• Dwarf Planets: Such as Pluto, Ceres, Eris, Makemake, and Haumea.
• Other Small Bodies: Includes asteroids, comets, and trans-Neptunian objects.
• Belts and Clouds: Asteroid belt, Kuiper belt, and the Oort cloud.

The planets orbit the Sun in elliptical paths. The asteroid belt lies between Mars and Jupiter. Beyond Neptune lies the Kuiper Belt and the scattered disc. Farther out is the Oort cloud, which is believed to be the source of long-period comets.
