To help compare different orders of magnitude, this page lists distances starting at 10²¹ m (1 Zm or 110,000 light years). An order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it. ... The distance between two points is the length of a straight line segment between them. ... The metre (Commonwealth English) or meter (American English) (symbol: m) is the SI base unit of length. ... A zettametre (American spelling: zettameter) (symbol: Zm) is a unit of length equal to 1021 metres. ... A light year, abbreviated ly, is the distance light travels in one year: roughly 9. ...

• Distances shorter than 10²¹ m
• 1 Zm = 1000 Em — 105,700 light years
• 1.7 × 10²¹ m — 179,000 light years — Distance from the Sun to the Large Magellanic Cloud.
• 2.0 × 10²¹ m — 210,000 light years — Distance from the Sun to the Small Magellanic Cloud.
• 8.5 × 10²¹ m — 900,000 light years — Distance from the Sun to the Leo I Dwarf Galaxy, furthest known Milky Way satellite galaxy.
• Distances longer than 10²² m

To help compare distances at different orders of magnitude this page lists lengths from 11,000 light years and 110,000 light years (1020 m and 1021 m). ...
