Earth's Scale in the Milky Way

This is a conceptual 3D visualization. Showing Earth and the Milky Way to true scale in one view is impossible.

Use your mouse/touch to Orbit (left-click/drag), Zoom (scroll/pinch), and Pan (right-click/two-finger drag).

Milky Way Galaxy (Approximate):

• Diameter: ~100,000 - 200,000 light-years
• Stars: ~100 - 400 billion
• Our Sun's distance from center: ~27,000 light-years

Solar System (Approximate):

• Diameter (Oort Cloud): ~2 light-years
• Distance Earth-Sun (1 AU): ~8.3 light-minutes

Earth:

• Diameter: ~12,742 km (~0.00000000135 light-years)

The yellow marker indicates the approximate location of our Sun. The surrounding star field represents the galaxy.

Perspective: If the Milky Way were the size of North America, our entire Solar System (out to the Oort cloud) would be roughly the size of a coffee cup. Earth itself would be much smaller than a single atom.
