To help compare different orders of magnitude, this page lists distances starting at 10 Ym (1025 m or 1.1 billion 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 10 Ym * 13.7 Ym — 1.37 billion light-years — Length of the Sloan Great Wall * 18 Ym — redshift 0.16 — 1.9 billion light-years — Distance to the quasar 3C 273 (light travel distance) * 33 Ym — 3.5 billion light-years — Maximum distance of the 2dF Galaxy Redshift Survey (light travel distance) * 37.8 Ym — 4 billion light-years — Length of the Huge-LQG, one of the largest and most massive known cosmic structure. * 75 Ym — redshift 0.95 — 8 billion light-years — Approximate distance to the supernova SN 2002dd in the Hubble Deep Field North (light travel distance) * 85 Ym — redshift 1.6 — 9 billion light-years — Approximate distance to the gamma ray burst GRB 990123 (light travel distance) * 94.6 Ym — billion light-years — Approximate distance to quasar OQ172 Distances longer than 100 Ym ==See also== *Orders of magnitude (length) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「10 yottametres」の詳細全文を読む スポンサード リンク
