1 E21 m

To help compare distances at different orders of magnitude this page lists lengths from 110,000 light years and 1,100,000 light years (10²¹ m and 10²² m). See also lengths of other orders of magnitude.

Distances shorter than 10²¹ m
52 kiloparsecs or 1.6 × 10²¹ m -- distance to the Large Magellanic Cloud (a dwarf galaxy orbiting the Milky Way)
54 kiloparsecs or 1.66 × 10²¹ m -- distance to the Small Magellanic Cloud (another dwarf galaxy orbiting the Milky Way)
Distances longer than 10²² m
