This planet is in the constellation Eridanus, and is about 810 light-years from Earth. Host starWASP-79, or CD-30 1812, is a F-type dwarf star located at 240 parsecs (810 light years) away from Earth. With {{solar mass|1.38|link=y}} and {{solar radius|1.53|link=y}}, it is both larger and more massive than the Sun. Its effective temperature is 6,600 K, making it hotter than the Sun.[1] CharacteristicsWASP-79b is a very large hot jupiter that is among the largest exoplanets discovered although its size is uncertain. It is most likely to be larger at {{jupiter radius|2.09 ± 0.14|link=y}} (approximately 300,000 kilometers across) with a temperature of 1,900 ± 50 K. However, it could be as small as {{jupiter radius|1.7 ± 0.11}} (approximately 240,000 kilometers across), which is comparable to the size of another hot jupiter WASP-78b, with a temperature at 1,770 ± 50 K. Even if bigger than Jupiter, its mass is slightly less massive than Jupiter.[1] {{clear}}See also
