Lengths with order of magnitude 1e17m: yellow Vernal Point arrow traces hundred light year radius circle with smaller ten light year circle at right; globular cluster Messier 5 in background; 12 light year radius Orion Nebula middle right; 50 light year wide view of the Carina Nebula bottom left; Pleiades cluster and Bubble nebula with similar diameters each around 10 light years bottom right; grey arrows show distances from Sun to stars Aldebaran (65 light years) and Vega (25 light years).

To help compare different distances this page lists lengths between 1017 m (100 Pm or 11 light years) and 1018 m (110 light years).

Distances shorter than 100 Pm

  • 110 Pm — 12 light years — Distance to Tau Ceti
  • 240 Pm — 25 light years — Distance to Vega
  • 260 Pm — 27 light years — Distance to Chara, a star approximately as bright as our Sun. Its faintness gives us an idea how our Sun would appear when viewed from even so close a distance as this.
  • 350 Pm — 24 light years — Diameter of the Orion Nebula[1][2]
  • 350 Pm — 37 light years — Distance to Arcturus
  • 400 Pm — 42 light years — Distance to Capella
  • 620 Pm — 65 light years — Distance to Aldebaran
