Stellar properties WASP-20 is a star of spectral type F9, aged 3.6 billion years. Its mass is for a radius of , or a density of .
Planetary system WASP-20b is a transiting hot Jupiter discovered in 2014. WASP-20b orbits WASP-20 in less than five Earth days very close to its star (0.06 AU) in a circular (near-zero eccentricity) orbit. The orbit is inclined by relative to the plane of the sky and is thus edge-on, as necessary for a transit to be observed.
