WASP-79b is an extrasolar planet orbiting the star CD-30 1812. This planet is in the constellation Eridanus, and is about 810 light-years from Earth.
Host star
WASP-79, or CD-30 1812, is a F-type dwarf star located at 240 parsecs (810 light years) away from Earth. With 1.38 M☉ and 1.53 R☉, it is both larger and more massive than the Sun. Its effective temperature is 6,600 K, making it hotter than the Sun.[1]
Characteristics
WASP-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 2.09 ± 0.14 RJ (approximately 300,000 kilometers across) with a temperature of 1,900 ± 50 K. However, it could be as small as 1.7 ± 0.11 RJ (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. Despite being larger than Jupiter, its mass is slightly less massive.[1]
In 2019, the transmission spectrum of WASP-79b was taken, with best fit being the hazy atmosphere containing water and Iron(I) hydride.[2]
