100 petametres

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 (106 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
