Distant Planet Has High Temperature of 1226C
The NASA Spitzer Space Telescope was used to study the changing weather on HD 80606b — a first for a planet outside of our solar system. It also has a very distinct orbit, as it comes closer to its sun than Mercury’s distance from the Earth’s sun, before launching away to be just as far as Earth is from the sun.
When it’s closest to the sun, radiation is 800 times stronger than when it is orbiting far away from the sun. The planet orbits the star in 111 days. The extremely high heat and severe temperature changes obviously make it unlikely any signs of life exist on the planet.
