About this world
HATS-7 b is a Neptune-like planet orbiting HATS-7, an orange dwarf (type K2) 785 light-years from Earth. It is about 0.56 times the size of Jupiter and holds 0.12 Jupiter masses. It completes an orbit every 3.19 days at 0.04 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,084 K (811 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium. Its atmosphere has already been studied in one spectroscopic observation.
It was discovered in 2015 by transit with HATSouth. A planet crosses its star and dims it by a tiny, periodic fraction.
