1 zettametre

The zettametre (SI symbol: Zm) is a unit of length in the metric system equal to 10²¹ metres.

To help compare different orders of magnitude, this page lists distances starting at 1 Zm (10²¹ m or 110,000 light years).

Distances longer than 1 Zm

• 1.7 Zm — 179,000 light years — Distance to the Large Magellanic Cloud, largest satellite galaxy of the Milky Way
• 2.0 Zm — 210,000 light years — Distance to the Small Magellanic Cloud
• 2.8 Zm — 300,000 light years — Distance to the Intergalactic Wanderer, one of the most distant globular clusters of Milky Way
• 8.5 Zm — 900,000 light years — Distance to the Leo I Dwarf Galaxy, farthest known Milky Way satellite galaxy
