WASP-35
Star in the constellation Eridanus From Wikipedia, the free encyclopedia
WASP-35 is a G-type main-sequence star about 660 light-years away. The star's age cannot be well constrained, but it is probably older than the Sun. WASP-35 is similar in concentration of heavy elements compared to the Sun.[6]

The star has no detectable starspot activity.[4] An imaging survey in 2015 found no detectable stellar companions,[7] although a spectroscopic survey in 2016 yielded a suspected red dwarf companion with a temperature of 3800±1100 K.[8]
Planetary system
In 2011 a transiting hot Jupiter planet b was detected. The planet's equilibrium temperature is 1450±20 K.[4]
