Waspie_Dwarf Posted February 27, 2017 #1 Share Posted February 27, 2017 Most Planets are Colder than Thought There Might be More Planets in the Habitable Zone Quote A common assumption in the search for habitable abodes beyond Earth is that the average temperature of planets always increases the more elliptical their orbit is. Now, scientists from the Planetary Habitability Laboratory (PHL) and the Arecibo Observatory in Puerto Rico have shown that planets in elliptical orbits are generally colder than previously believed. Planets can move around their parent star in orbits that are not perfectly circular. These elliptical orbits put planets sometimes significantly closer or farther from their star, thus contributing to extreme temperature changes. This is not the case of Earth, and probably for the exoplanets orbiting the stars Proxima Centauri or TRAPPIST-1, but true for many known planets around other stars.
