Lengths with order of magnitude 1e18m: thousand light year radius circle with yellow arrow and 100 light year circle at right with globular cluster Messier 5 within and Carina Nebula in front; globular cluster Omega Centauri to left of both; part of the 1400 light year wide Tarantula Nebula fills the background.

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 105.7 light years) and 10¹⁹ m (1057 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
