It is a planet astronomers say probably should not even exist.
Researchers said on Monday they have spotted a truly extreme planet beyond our solar system, a blazingly hot world a bit bigger than Neptune that orbits a sun-like star every 19 hours and appears to be wrapped in metallic clouds made of titanium and silicates that reflect most incoming light back into space.
The planet's diameter is about 4.7 times greater than Earth, and it orbits very close to its star - closer than our solar system's innermost planet Mercury's distance to the sun and 60 times closer than Earth's orbit. With blistering solar radiation from its star, its surface temperature is about 3,270 degrees Fahrenheit , hotter than molten lava.
Possessing an atmosphere while orbiting so close to its star makes it "a planet that shouldn't exist," according to astronomer and study co-author Vivien Parmentier of the Côte d'Azur Observatory in France. All previously known planets that orbit their stars in less than one Earth day were either "hot Jupiters," gas giants similar in composition to our solar system's largest planet but much hotter due to solar radiation - or rocky planets smaller than Earth and lacking an atmosphere.
