How heavy is the Sun?

The sun is over 300,000 times heavier than the earth!

Although we cannot actually weigh the Sun with a scale, we can compute its weight by studying the way it affects other objects, like the Earth. We do know that it contains virtually all the mass in our solar system! 

We can also understand this better by making some comparisons. Since the Sun is so much more massive than the Earth, its gravitational pull is also much larger. That means a child who weighs 75 pounds on Earth would weigh about a ton on the Sun.
