WASP-1 is a star in the constellation Andromeda . The star is accompanied by a transit planet called WASP- 1b.
The star has about 1.2 times the solar mass and has an apparent magnitude of 11.8 mag. It is of the spectral type F7 V, its surface temperature is approximately 6200 Kelvin, which makes it very similar to the sun.
Planetary companion
WASP-1b was provided during the SuperWASP - Surveys as exoplanets identified -Kandidat and later using the radial velocity method confirmed. It has a mass of about 89 percent of the mass of Jupiter . Since the planet orbits its star very closely - the distance is 0.0382 (± 0.0013) astronomical units , i.e. about four percent of the distance between the earth and the sun - it only needs 2.51997 (± 0.00016) for one orbit Days. The radius of the exoplanet is about 1.4 Jupiter radii.
