... Using Newton’s Laws of Motion we can calculate the Sun’s mass = 2 x 1030 kg (the Sun constitutes 99.85% of the total mass of the solar system) Mass divided by volume gives us the Sun’s average density = 1410 kg per cubic metre The Sun is made up of gas - it is too hot to be liquid. PHYS1142 ...

... The end of the life cycle of really massive stars is different to that of massive stars. After a really massive red giant collapses in a supernova explosion, it leaves a star so dense that not even light can escape its gravitational pull. This is called a black hole! Some scientists believe that the ...
