A planet hotter than most stars

With a day-side temperature of 4,600 Kelvin (more than 7,800 degrees Fahrenheit), planet KELT-9b is hotter than most stars, and only 1,200 Kelvin (about 2,000 degrees Fahrenheit) cooler than our own sun.
In this week's issue of the journal Nature and at a presentation at the American Astronomical Society spring meeting, an international research team led by astronomers at The Ohio State University and Vanderbilt University describes a planet with some very unusual features.

Furthermore, most worlds orbiting such hot stars have no chance of being habitable, so the search for exoplanets has largely focused on dimmer, cooler stars in recent years.
