Star system, 1,400 light-years

WASP-12 and its one planet

WASP-12 b is an exoplanet 22.026 times Earth's width, about 2.0 times Jupiter's, 1,400 light-years away, orbiting closer to its star than the habitable zone we compute for it.

WASP-12 is a star of spectral type the table does not record, 1,400 light-years from us, with one known planet.

It was found as a small, regular dip in its star's light each time it crosses in front of it in 2008. Its orbit is closer to its star than the habitable zone computed for it. The Archive's own distance for it is 0.0234 au; the three papers behind its period, its star's mass and that distance do not agree with Kepler's third law, so the page uses the one the period and the star's mass give.
