Exoplanetary Scratchpad

[SysBP Img]

System containing one of four Kepler candidates that are 20 times closer to their star than Mercury is from the Sun. This planet could have a period of 4.2 hours, with surface temperature of 4,200F. Surfaces on these planets would be molten on the day time, while "rock snow" may fall on the night side. In order for a planet to survive at this distance and heat, it would have to be made of almost completely iron. Planet is actually inside its star's corona, which would expose it to lethal particles even on the night side, which would irradiate the surface and make it glow. Not confirmed, but astronomers are confident in its existence.
