To help compare different orders of magnitude, this page lists distances starting at 10²⁰ m (100 Em or 11,000 light years).

Distances shorter than 10²⁰ m

• 1.5×10²⁰ m — 16,000 light years — Diameter of the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way
• 2.0×10²⁰ m — 21,500 light years — Distance to OGLE-2005-BLG-390Lb, the most distant and the most Earth-like planet known
• 2.4×10²⁰ m — 25,000 light years — Distance to the Canis Major Dwarf Galaxy
• 2.6×10²⁰ m — 28,000 light years — Distance to the center of the Galaxy
• 8.3×10²⁰ m — 88,000 light years — Distance to the Sagittarius Dwarf Elliptical Galaxy
• 9.5×10²⁰ m — 100,000 light years — Diameter of the disc of the Milky Way Galaxy
