This is a list of two types of planets: standard planets and dwarf planets, in the Solar System.

Planets in the Solar System

  • Terrestrial planets
    • Mercury – The planet with the second highest temperature in the Solar System and the closest planet to the Sun.
    • Venus – The warmest planet. Sometimes called "Earth's twin" because Venus and Earth are very similar.
    • Earth – The only planet that is known to have life. It has one natural satellite, the Moon.
    • Mars – Sometimes called the "red planet".
    • Phaeton – a planet that some think broke apart to form the asteroid belt, though most astronomers think it never formed.
    • Pluto – (disputed) Historically considered the smallest planet, Pluto is now considered a "dwarf planet" by the International Astronomical Union (IAU) when they developed a definition for "planet" on August 24, 2006. Other organizations disagreed.
  • Gas giants
    • Jupiter – The largest planet in the Solar System.
    • Saturn – Sixth planet from the Sun. It has giant rings around it.
    • Uranus - Seventh planet from the Sun. It has 11 rings around it.
    • Neptune – The farthest planet that we know from the Sun.
    • Planet Nine – a hypothetical gas giant planet beyond Neptune. It has not been found, but some astronomers think its gravity pulls on the orbits of many dwarf planets.
