WASP-5 is a star about 300 parsecs (about 1000 light-years ) away that is orbited by an exoplanet . The star in the constellation Phoenix belongs to the spectral class G4 V and has an apparent magnitude of 12.3 mag. With a surface temperature of approx. 5700 Kelvin, the star is similar to the sun, and its age (approx. 3–4 billion years) is in the range of the sun's age.
Planetary companion
The exoplanet with the systematic name WASP-5 b was discovered with the help of the transit method as part of the SuperWASP project through observations in 2006 and 2007 (Anderson et al., 2008). It has an orbital period of 1.63 days, its mass corresponds to 1.6 Jupiter's masses and its radius 1.2 Jupiter radii. The major semi-axis of the orbit measures approx. 0.027 astronomical units .
