Hot Jupiter
Hot Jupiters (also called roaster planets, epistellar jovians, pegasids or pegasean planets) are a class of extrasolar planets whose characteristics are similar to Jupiter, however, with high surface temperatures because they orbit very close to their parent stars, between approximately 0.015 and 0.5 astronomical unit (2.2×106 and 75×106 km) of their parent stars, while Jupiter orbits its parent star (the Sun) at 5.2 astronomical units (780×106 km), causing low surface temperatures.
One of the most well-known hot Jupiters is 51 Pegasi b, nicknamed Bellerophon. Discovered in 1995, it was the first extrasolar planet found orbiting a Sun-like star.
