WASP-55

WASP-55 is a G-type main-sequence star about 980 light-years away. The star is much younger than the Sun at approximately 1.1+0.8
−0.6
 billion years
. WASP-55 is similar to the Sun in concentration of heavy elements.

A multiplicity survey in 2016 found one candidate stellar companion to WASP-55 at a projected separation of 4.435±0.018. Follow-up observations in 2017 were unable to confirm if the suspected companion red dwarf star, with a temperature of 3,340±90 K, is gravitationally bound to WASP-55 or not.

Planetary system

In 2012 a transiting hot Jupiter planet b was detected on a tight, circular orbit. Its equilibrium temperature is 1,305 K.
