System 400 ly awaycontaining a Hot Terran planet most similar Earth's mass (1.86 ME), diameter (1.16 RE), density (5.3 vs Earth's 5.5) and composition in 2013. This is the smallest planet whose size and mass have been measured, and is likely made of mostly rock and iron. Its star is 73% as large as the sun, and it orbits every 8.5 hours, has a temperature of more than 2000C than Earth, and likely has a molten surface. It has the tightest orbit confirmed. It will eventually be broken up by its star and vaporize. A mystery is how it got there, since if it had formed where it is now, it would now be inside the star, which used to be larger. A bright enough planet to be observed by the largest earth-based telescopes. The surface is so hot that shines brightly in visible light, which can be isolated from the star.
