  Gas giant

  A gas giant (sometimes also known as a Jovian planet after the planet Jupiter, or giant planet) is a large planet that is not primarily composed of rock or other solid matter. There are four gas giants in our Solar System: Jupiter, Saturn, Uranus, and Neptune. Many extrasolar gas giants have been...

  Terrestrial planet

  A terrestrial planet, telluric planet or rocky planet is a planet that is primarily composed of silicate rocks. Within the solar system, the terrestrial planets are the inner planets closest to the Sun. The terms are derived from Latin words for Earth (Terra and Tellus), and an alternative...

  Desert planet

  In science fiction, a desert planet is a one-climate planet where the climate is desert, with little or no natural precipitation. The motif is a common one, and includes both real and fictional planets. In a few stories, the motif is accompanied by elements of hydraulic despotism. Perhaps the most...

  Pulsar planet

  Pulsar planets are planets that are found orbiting pulsars, or rapidly rotating neutron stars. The first such planet to be discovered was around a millisecond pulsar and was the first extrasolar planet to be discovered. Pulsar planets are discovered through pulsar timing measurements, to detect...

  Hot Jupiter

  Hot Jupiters (also called oven roasters, epistellar jovians, pegasids or pegasean planets) are a class of extrasolar planet whose mass is close to or exceeds that of Jupiter (1.9 × 10 kg), but unlike in the Solar System, where Jupiter orbits at 5.2 AU, the planets referred to as hot Jupiters orbit...

  Eccentric Jupiter

  An Eccentric Jupiter is a Jovian planet that orbits its star in a highly eccentric orbit, much like a comet. Eccentric Jupiters may disqualify a planetary system from having earth-like planets in it because a massive and highly eccentric gas giant may remove all earth mass planets from the...

  Ocean planet

  An ocean planet is a hypothetical type of planet whose surface is completely covered with an ocean of water. Planetary objects that form in the outer solar system begin as a comet-like mixture of roughly 50% water and 50% rock by weight. Simulations of solar system formation have shown that planets...
