Exoplanetary Scratchpad

[SysBP Img]

A sunlike star about 500 light years away with two Hot Super Earths (and possibly a third), including the first detected transiting Super-Earth. It a diameter about twice that of the Earth. First exoplanet with evidence of a solid surface and does not possess a thick atmosphere. Because its star is active, its mass is somewhat uncertain (2.3 to 8.5 ME), which makes it unclear if the planet actually has a solid surface. Also the closest exoplanet to its star known and has the smallest orbit period (0.85 Earth Days). Likely the first Super-Io discovered (due to slight eccentricity) and the first gas giant remnant core found. Has temperature of 1000-1500C. Planet c is a larger Neptunian orbiting further away and does not transit.
