The Planet

Main article: WASP -4 b

Due to the large number of newly found, extrasolar planets are awarded newfound companions no longer proper names. Wherefore the name of the planet, which WASP -4 orbits, just "b", so WASP -4b. WASP -4b has at least 1.34 Jupiter masses, has about one and a half times the radius of Jupiter and needs for the orbit to its star 1.34 days. Since direct observation of the planet due to the large distance and high brightness difference is impossible to his star with today's technical resources, most sizes are minimum and maximum sizes. Thus, the distance of the planet to its star, which corresponds to about 2.3 % of the distance, which has the earth from the sun, a resultant from the data and not directly observed quantity.
