WASP-14b is an
extrasolar planet discovered in 2008 by
SuperWASP
WASP or Wide Angle Search for Planets is an international consortium of several academic organisations performing an ultra-wide angle search for exoplanets using transit photometry. The array of robotic telescopes aims to survey the entire sky, ...
using the
transit method. Follow-up radial velocity measurements showed that the mass of WASP-14b is almost eight times larger than that of
Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but ...
. The radius found by the transit observations show that it has a radius 25% larger than Jupiter. This makes WASP-14b one of the densest exoplanets known.
Its radius best fits the model of
Jonathan Fortney.
Orbit
First calculation of WASP-14b's
Rossiter–McLaughlin effect and so spin-orbit angle was −14 ± 17 degrees. It is too eccentric for its age and so is possibly pulled into its orbit by another planet.
The study in 2012 has updated spin-orbit angle to 33.1°.
