How heavy is the Sun?
Although we can not actually weigh the Sun with a scale we can compute its weight by studying how it affects other objects like the Earth. We do know that it contains all the mass in our Solar System. Since the Sun is so much more massive than the Earth, over 300 000 times heavier, its gravitational pull is also much larger. A child that weighs 75 pounds on Earth would weigh a ton on the Sun.
