New planet found to be hotter than most stars

New planet found to be hotter than most stars

A newly discovered Jupiter-like world, announced in June 2017, is so hot that even its nights are like the flame of a welding torch. This gas giant has a “year” only 1.5 days long, and may have a tail like a comet. Planet KELT-9b is hotter than most stars. With a day-side temperature of more than 7,800 degrees Fahrenheit, it is only about 2,000 degrees Fahrenheit cooler than our own sun. The discovery team's member from Penn State is Thomas Beatty, of Penn State's Department of Astronomy and Astrophysics.
