10 yottametres

To help compare different orders of magnitude, this page lists distances starting at 1025 m (10 Ym or 1.1 gigalight-years). At this scale, expansion of the universe becomes significant. Distance of these objects are derived from their measured redshifts, which depends on the cosmological models used.

Distances shorter than 1025 m
