A curious fact about the structure of the planet Jupiter, compared to that of Earth, is that it has - much greater mass but much lower average density. A good example of a positive feedback effect in global warming is that melting sea ice causes a decrease in the Earth's albedo, meaning we absorb more sunlight than ever. T/F - T A main sequence star of mass 3 M☉has a luminosity of approximately 50 L☉. How long is the Main Sequence phase for such a star? - 6 x 10^8 years A planet can o...
