WASP-16b is an extrasolar planet that travels around its star, WASP-16, every 3.12 days. Likely a hot Jupiter. Its mass is near .855 of Jupiter, the radius is 1.008 of Jupiter. It was discovered in 2009 by a team led by T.A. Lister as part of the Wide Angle Search for Planets project.[1]

Characteriscics

In 2012, it was found from the Rossiter–McLaughlin effect that WASP-16b orbits its slow-rotating and likely old parent star WASP-16 in a prograde direction, with the star's rotational axis inclined to the planetary orbit by −4.2°+11.0°
−13.9°
