Size comparison of WASP-12b (gray) with Jupiter.
 Quote by Wikipedia WASP-12 is a magnitude 11 yellow dwarf star located approximately 600 light-years away in the constellation Auriga. WASP-12 has a mass and radius similar to the Sun at 1.35 $M_{\odot}$. WASP-12b is an extrasolar planet, discovered by the SuperWASP planetary transit survey orbiting the star WASP-12. Its discovery was announced on April 1, 2008. Due to its extremely close orbit to its star, its radius is 79% larger than Jupiter's and its mass 41% larger. The planet takes only a little over a day to orbit the star, in contrast to 365 days for the Earth to orbit the Sun. Its distance from the star is only 1/44 the Earth’s distance from the Sun with the eccentricity the same as Jupiter. The planet is so close to WASP-12 that the star's tidal forces are distorting the planet into an egg shape and pulling away its atmosphere at a rate of about 10−7 MJ (about 189 million billion tonnes) per year. The so-called "tidal heating", and the proximity of the planet to its star, combine to bring the surface temperature to more than 2,500 K (2,200 °C). On 20 May 2010, the Hubble Space Telescope spotted WASP-12b being consumed by its star. Despite scientists already being aware that stars can consume planets, this is the first time such an event has been spotted so clearly.
 Quote by Associated Free Press The Hubble space telescope has discovered a planet in our galaxy in the process of being devoured by the star that it orbits, according to a paper published in The Astrophysical Journal Letters. The doomed planet, dubbed WASP-12b, has the highest known surface temperature of any planet in the Milky Way -- around 1,500 degrees Celsius (2,800 degrees Fahrenheit). But it could be enveloped by its own parent star over the next ten million years, the paper's authors have concluded.
