To help compare different orders of magnitude, this page lists lengths starting at 10⁸ m (100 Mm or 100,000 km).

Distances shorter than 10⁸ m

• 102,000 km — Diameter of HD 149026 b, an unusually dense Jovian planet
• 111,191 km — 20,000 (nautical, British) leagues (see Jules Verne)
• 120,000 km — Diameter of Saturn
• 140,000 km — Diameter of Jupiter
• 174,000 km — Diameter of OGLE-TR-122b, the smallest known star
• 180,000 km — Diameter of HD 209458 b, the largest known planet
• 202,080 km — Coastline of Canada^{[citation needed]}
• 280,000 km — Diameter of Proxima Centauri, a typical red dwarf
• 299,792 km — One light second; the distance light travels in vacuum in one second (see speed of light)
• 384,300 km (238,840 mi) — Average Earth-Moon distance
