To help compare different orders of magnitude, this page lists lengths starting at 10⁸ metres (100 megametres or 100,000 kilometres or 62,150 miles).

Distances shorter than 10⁸ metres

• 102 Mm — Diameter of HD 149026 b, an unusually dense Jovian planet
• 111.191 Mm — 20,000 (nautical, British) leagues (see Jules Verne, Twenty Thousand Leagues Under the Sea)
• 120 Mm — Diameter of Saturn
• 140 Mm — Diameter of Jupiter
• 174 Mm — Diameter of OGLE-TR-122b, the smallest known star
• 180 Mm — Diameter of TrES-4, the largest known planet
• 196 Mm — Diameter of Proxima Centauri, a typical red dwarf
• 299.792 Mm — One light second; the distance light travels in vacuum in one second (see speed of light)
• 384.4 Mm (238,855 mi) — Average Earth-Moon distance
