Can our star retain its dominance beyond the solar system? This means the sun is almost exactly three orders of magnitude, or 1,000 times, more massive than the gas giant. Jupiter has a mass of 4.2 × 1027 lbs (1.9 × 10²⁷ kgs), according to NASA. Of these planets, the most massive is Jupiter, which is also the second most massive object in the solar system after the sun. Around 4.6 billion years ago a disk of gas and dust collapsed to birth our star and what material didn't go into the sun was leftover as a planetary nebula from which the planets emerged. Of all the mass contained within the solar system, NASA says that 99.8% of it is locked up in the sun. ![]() To get a picture of just how massive this makes our star we can compare that to the planets and the solar system as a whole. So the mass of a rubber ball on Earth would remain the same on the moon, but its weight would change because of the reduction in gravitational pull. ![]() Mass and weight are distinct because weight is a measure of the size of the pull of gravity on the object.
