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.[8]
The star has no detectable starspot activity.[9] An imaging survey in 2015 found no detectable stellar companions,[10] although a spectroscopic survey in 2016 yielded a suspected red dwarf companion with a temperature of 3800±1100 K.[11]
Planetary system
[edit]In 2011 a transiting hot Jupiter planet, WASP-35b, was detected. The planet's equilibrium temperature is 1450±20 K.[9]
