Objects with size order of magnitude 1e16m: Ten light years (94.6 Pm) radius circle with yellow Vernal Point arrow; Bubble Nebula (NGC 7635), left; Dumbbell Nebula (NGC 6853), right; one light year shell lower right with the smaller Cat's Eye Nebula (NGC_6543) and Barnard 68 adjacent.
1e16m lengths: Ten light years (94.6 Pm) yellow shell; Sirius below right; BL Ceti below left; Proxima and Alpha Centauri upper right; light year shell with Comet 1910 A1's orbit inside top right
To help compare different distances this page lists lengths starting at 1016 m (10 Pm or 66,800 AU, 1.06 light years).
- 15 Pm — 1.59 light years — Possible outer radius of Oort cloud
- 20 Pm — 2.11 light years — maximum extent of influence of the Sun's gravitational field
- 30.9 Pm — 3.26 light years — 1 parsec
- 39.9 Pm — 4.22 light years — Distance to Proxima Centauri (nearest star to Sun)
- 81.3 Pm — 8.59 light years — Distance to Sirius
