Script error: No such module "Check for unknown parameters".

WASP-3 is a triple star system located about Script error: No such module "convert". away from the Sun in the constellation Lyra. The system has an apparent magnitude of 10. The brightest and most massive star of this system is WASP-3A, an F-type main sequence star which has one known transiting hot Jupiter exoplanet, WASP-3b. Since the planet transits the star, the star is classified as a planetary transit variable and has received the variable star designation V838 Lyrae.[7]

Triple system

WASP-3 has been identified as a triple star system in a 2019 study of astrometry from the Gaia mission.[11]Template:Rp The brightest and most massive component of the system is WASP-3A, an F-type main sequence star that is 1.24 times as massive as the Sun and 1.31 times as large as the Sun in radius.[9]Template:Rp WASP-3A appears to be a variable star; observations between 2007 and 2010 show that the star's chromospheric activity had increased during that time period.[12] The second companion, WASP-3B, is a low-mass star about 0.11 times as massive as the Sun and has an effective temperature of about Script error: No such module "val"..[8]Template:Rp WASP-3B is separated eastward from WASP-3A at an angular separation of approximately 1.19 arcseconds, corresponding to a projected separation distance of about Script error: No such module "val"..[8]Template:Rp WASP-3B was first identified in observations from 2012 to 2013.[8]Template:Rp The third companion, WASP-3C, is much more distant with an angular separation of approximately 18.3 arcseconds from WASP-3A, corresponding to a projected separation distance of Script error: No such module "val"..[11]Template:Rp WASP-3C is about 0.77 times as massive as the Sun and has an effective temperature of about Script error: No such module "val"..[6]

Planetary system

WASP-3A has one known transiting hot Jupiter extrasolar planet, WASP-3b, which was detected by the SuperWASP project in 2007.[9] It was confirmed in 2008 by observations from the William Herschel Telescope.

In 2010, researchers proposed a second planet orbiting WASP-3A due to transit timing variations in WASP-3b.[13][14] But in 2012 this proposal was refuted.[12]
