Planets Can Alter Each Other's Climates over Eons
Moffet Field CA (SPX) Feb 26, 2015
A new study sheds light on how exoplanets in tightly-packed solar systems interact with each other gravitationally by affecting one another's climates and their abilities to support alien life. Because the exoplanets are so close to one another in these compact solar systems, they have tidal influence, much like the Earth and the Moon have on each other. The tides modify the spin rates, axial tilts and orbits of these planets over time, and therefore alter their climates. The study examines ... read more
