The sun's mass makes up about 99.86% of the entire mass of the solar system.

The sun has the mind-boggling mass of approximately 1,989,000,000,000,000,000,000,000,000,000 kg (one nonillion, nine hundred eighty nine octillion kilograms). This is extremely close to the mass of the solar system as a whole. In contrast, the largest planet, Jupiter, with its mass of about 1,899,000,000,000,000,000,000,000,000 kg (one octillion eight hundred ninety-nine septillion kilograms), makes up a teeny-tiny 0.09% of the solar system!
