F8 star also known as GSC 03547-01402 containing a transiting Hot Jupiter and an outer Jovian and a further out stellar companion. Transiting planet was used as a test for the Kepler mission (dubbed Kepler 2), which was able to detect the planet's occulation, as well as evidence of phases. Very little of its heat is transported to its night side, with its hottest spot being 1,300 F hotter than its coldest spot. Its atmosphere could be made up of exotic gases like Titanium Oxide. The Hubble Space Telescope made its 1,000,000th science observation on this planet in the attempt to detect water in its atmosphere. The planet may "lift" its stars surface up gravitationally, reducing its temperature a fraction of a degree in a darkened spot that lags a few hours behind the planet. It was found by a Japanese team to be orbiting backwards only a day after the first retrograde exoplanet WASP-17b was announced. The Japanese team inspected two stars nearby, measured their proper motions, and found that one of them was a member of the system. They also confirmed an outer radial velocity detected Jovian between the planet c and companion star B. Star B is suspected of tilting planet c's orbit, which in turn affected planet b's orbit and caused it to orbit backwards.
