How big is the Sun compared to Earth?
Data as of July 2026
1.3 millionEarths fit inside
The Sun is 109 times wider than Earth: 1,392,700 km against 12,742 km. Because volume scales with the cube of width, about 1.3 million Earths would fit inside it.

A scale model you can hold in your head
Shrink the Sun to a grapefruit about 14 cm wide. On that scale, Earth is a grain of sand just over a millimetre across: sitting 15 metres away. Jupiter is a 14 mm marble at 78 metres. Neptune is a 5 mm pea nearly half a kilometre from the grapefruit. And the next grapefruit, the nearest star, is roughly 4,000 km away.
Almost every picture of the solar system you've ever seen lies about this, because it has to: draw the Sun and Earth at their true relative sizes and distance on one page, and Earth is invisible. That's exactly what the interactive view's 1:1 mode shows: honestly.
The Sun loses four million tonnes of itself every second, converted to light. It has been doing that for 4.6 billion years, and has burned through only about 0.03% of its mass.
