To help compare distances at different
orders of magnitude this page lists lengths starting at 10
20 m (11,000
light years).
- Shorter distances
- 16,000 light years = 1.5 * 1020m -- diameter of the [Small Magellanic Cloud]? (a dwarf galaxy orbiting the Milky Way)
- 28,000 light years = 2.6 * 1020m -- distance from the Sun to the center of the Galaxy.
- 100,000 light years = 9.5 * 1020m -- diameter of the disc of the Galaxy.
