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

  • 1.37×1025 m - Length of the largest known cosmic structure, the Sloan Great Wall.
  • 1.8×1025 m — redshift 0.16 — 1.9 gigalight-years — Distance to the quasar 3C 273 (light travel distance)
  • 3.3×1025 m — 3.5 gigalight-years — Maximum distance of the 2dF Galaxy Redshift Survey (light travel distance)
  • 7.5×1025 m — redshift 0.95 — 8.0 gigalight-years — Approximate distance to the supernova SN 2002dd in the Hubble Deep Field North (light travel distance)
  • 8.5×1025 m — redshift 1.6 — 9.0 gigalight-years — Approximate distance to the gamma ray burst GRB 990123 (light travel distance)

Distances longer than 1026 m
