1 Exametre

This list includes distances between 1 and 10 exametres (1018 m). To help compare different distances this page lists lengths between 1018 m (1 Em or 110 light years) and 1019 m (1100 light years).

Distances shorter than 1 Em

  • 1.4 Em — 145 light years — Diameter of Messier Object 13 (a typical globular cluster)
  • 1.6 Em — 172 ± 12.5 light years — Diameter of Omega Centauri (one of the largest known globular clusters, perhaps containing over a million stars)
  • 3.1 Em — 310 light years — Distance to Canopus according to Hipparcos
  • 6.1 Em — 640 light years — Distance to Betelgeuse according to Hipparcos
  • 6.2 Em — 650 light years — Distance to the Helix Nebula, located in the constellation Aquarius
  • 7.3 Em — 730 light years — Distance to Rigel according to Hipparcos
  • 9 Em — 1000 light years — Diameter of the Tarantula Nebula
