Exoplanet Upsilon Andromedae b. Animation showing the orbit of the gaseous exoplanet known as Upsilon Andromedae b. This extrasolar planet is approximately 44 light-years away from Earth in the constellation of Andromeda, and orbits the star, Upsilon Andromedae. It takes 4.5 days to orbit its star, and appears to be tidally locked, with the same side always facing the heat. It has an unusual hot spot on its surface. NASA' s Spitzer Space Telescope measured how the infrared light of the system changes during the planet's orbit and the data is displayed as a graph. Unexpectedly, the hot spot is not on the side facing the star but is rotated about 80 degrees towards the planet's boundary between day and night. | |
