- Please give the answer on units of solar masses, thank youarrow_forwardExplain the tidal hypothesis.arrow_forwardRead this main idea: The sun is the center of our solar system. Choose three details that go with the main idea. The sun's gravity holds the planets in place. It provides them with heat and light. The largest stars, called supergiants, are 1,500 times bigger than our sun. It takes Earth 365 days to orbit the sun. Jupiter takes 12 years! Our sun is not the largest or hottest star. It is a medium sized yellow star. Radio telescopes use radio waves to show stars in great detail. Astronomers long ago and today use star charts to map star locations. All of the planets in our solar system revolve around one star-our sun. Stars can be blue, white, yellow, or red. Blue stars are the hottest. A reflector telescope bounces star light through mirrors.arrow_forward
