Could we live on another planet? 0.0 / 5 ? PhysicsAstrophysicsASAll boards Created by: burns.hamishCreated on: 19-06-17 09:30 Whats up with our planet? Climate change overpopulation lack of food money - planets have resources we can use. 1 of 5 Traits a planet needs for life? Temperature H20 atmosphere - small gravity = can't hold atmosphere, particles escape n leave planet w/out protective atmosphere. sun nutrients - come about via volcanic systems. too volcanic = hard to get nutrients, but h20 n volcanos transport nutrients. 2 of 5 Potential Planets - Proxima B Rocky planet (like earth) in habital zone Orbits closest star to sun 3 of 5 Potential planets - Keplar-452b "earths cousin" orbits star v simmilar to own (same type, G2V) mean temp of -8 (slightly warmer than earth) larger than earth which will mean it'll keep its water, e.g. oceans, longer than earth. 26m years to get there 4 of 5 Potential Planets - Trappist-1e Part of the Trappist 1 system. orbits a red ultracool dwarf star, 8% mass of the sun, meaning it will live 400-500x as long as the sun. one of the last things in universe. 1 side perminntly facing sun, other in darkness. between 2 points = terminator line where temps could allow h20. if it has a thick atmosphere, could transfer heat around planet. 5 of 5
