What does it mean when it says more than 1 million to sit inside the sun but the some mass is only about 300000 times the mass of how is that possible?

Answer 1

The sun's mass is about 333,000 or about one third of a million times that of Earth, but the sun's volume is about 1.3 million times that of Earth. In other words, the sun is less dense than Earth. Mass is a measure of how much matter is in an object, not its size.
