Upsilon Andromeda b is tidally locked to its sun like the Moon is to Earth, so one side of the planet is always facing its star. This setup creates one of the largest temperature differences astronomers have ever seen on an exoplanet. One side of the planet is always hot as lava, while the other is chilled possibly below freezing.
