1 E25 m

To help compare different orders of magnitude, this page lists distances starting at 10²⁵ m (10 Ym or 1,100 million light 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

1.8×10²⁵ m — redshift 0.16 — 1,900 million light years — Distance to the quasar 3C273 (light travel distance)
3.3×10²⁵ m — 3,500 million light years — Maximum distance of the 2dF Galaxy Redshift Survey (light travel distance)
7.5×10²⁵ m — redshift 0.95 — 8,000 million light years — Approximate distance to the supernova SN 2002dd in the Hubble Deep Field North (light travel distance)
8.5×10²⁵ m — redshift 1.6 — 9,000 million light years — Approximate distance to the gamma ray burst GRB 990123 (light travel distance)
