Hot Jupiters are a class of extrasolar planets whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close – between approximately 0.015 and 0.5 astronomical units to their parent stars.
A hot Neptune is a type of giant planet with a mass similar to that of Uranus or Neptune in an orbit close to its star, normally less than 1 AU.
A Temperate Planet is a planet with environmental conditions similar to those found on the planet Earth.
An Arid Planet is a planet with environmental conditions similar to those found on the planet Earth but with less water, nearly dry.
A Moonlike Planet is a planet with no atmosphere. Temperatures may therefore vary from very cold to very hot.
