      The mass of the Sun is 1.989×10^30kg (that’s 1,989,000,000,000,000,000,000,000,000,000kg!), while the Earth weighs in at a comparatively svelte 5.972×10^24kg. So you’d need 333,054 Earths to match the mass of the Sun.

      Another way to imagine this is (in rough terms) to line up 10 Earths side by side. These would be the same diameter as Jupiter, the largest planet in the Solar System. If we then lined up 10 jupiters side by side, they’d stretch all the way from one side of the Sun to the other. This means that we would have to lien up 100 Earths to have the same diameter (roughly) as the Sun
