WASP-25 is a yellow main sequence star in the constellation of Hydra.

Star characteristics

WASP-25 is slightly metal-poor (85% of Solar amount) and is probably a young star which has just entered the main sequence.

Planetary system

The "Hot Jupiter" class planet WASP-25b was discovered around WASP-25 in 2010. The planet would have an equilibrium temperature of 1212{{±|35}} K.

A Rossiter-McLaughlin effect based study in 2011 found a modest misalignment of the planetary orbit to the rotational axis of the parent star, equal to 14.6{{±|6.7}} degrees.{{cite journal|arxiv=1203.4971|doi=10.1111/j.1365-2966.2012.20973.x|title=Rossiter-Mc Laughlin effect measurements for WASP-16, WASP-25 and WASP-31★|year=2012|last1=Brown|first1=D.
