The Orion Nebula
24 light-years — roughly how far across it is
Too small to see at this scale; ringed.
The Andromeda Galaxy
152,000 light-years — roughly how far across it is

The Andromeda Galaxy is 6,330 times as wide as The Orion Nebula.

A dashed outline is a rough width across something that is not round.

  • The Orion Nebula: Approximate: half the apparent size times the distance (the catalogue's note)
  • The Andromeda Galaxy: Approximate: half the apparent size times the distance (the catalogue's note)

Any distance, three ways

4.25 light-years:

  • Light4.25 years
  • Voyager 1's speed75,400 years
  • Driving at 100 km/h45.8 million years

Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling. The nearest star, Proxima Centauri, is 4.246 light-years away.
