http://www.bbc.com/news/science-environment-40171936 It takes just two (Earth) days for this tidally locked large planet, three times the mass and twice as big as Jupiter, to complete a polar orbit about the hot, UV emitting blue star more than twice as massive as our Sun, which is so rapidly spinning that it would appear to be flat to our eyes. The tidally locked surface on the day side of KELT-9b is over 4,300 degrees Celsius (7800 degrees F), which is hotter than Red Dwarf type stars, and only about 2000 degrees F cooler than our Sun. By means of comparison, the day side of our own planet Mercury is a cool 430 degrees Celsius (800 degrees F). Which is to say, Mercury isn't even luke warm compared to this. The planet was identified in 2014 as something of interest by a small robotic "Kilodegree Extremely Little Telescope" facility that uses standard camera telephoto lenses searching for exoplanets, but it has taken this long to confirm the odd behavior and characteristics of this system. Stars of this type rapidly burn and expend their nuclear fuel for millions (but not billions) of years, so when the host star begins to expand near the end of its lifecycle, this large exoplanet could provide a large pre-heated, ready-to-eat snack, if the surface of the planet hasn't sublimated and gotten completely blown away by solar wind, that is.
