The sun an average mass and sized star composed of hydrogen and helium gas. It generates energy in its core by nuclear fusion reaction. It is the only star in the solar system. Once all the fuel is run out, the nuclear fusion reaction would stop and the sun would die. There are billions of stars in our milky way galaxy and sun is not the largest of them.
Star 1 - 4 hours right ascension Star 2 - 3 hours right ascension Subtracting hours right ascension 4 hours right ascension - 3 hours right ascension = 1 hours right ascension. Thus, star 1 will rise 1 hour before star 2
