To help compare different distances this page lists lengths starting at 10 metres (1 gigametre (Gm) or 1 million kilometres).
Distances shorter than 10 metres
- 1.4 Gm — Diameter of Sun
- 1.5 Gm — (proposed) Expected orbit from Earth of the James Webb Space Telescope
- 2.19 Gm — Closest approach of Comet Lexell to Earth, happened on 1 July 1770; closest comet approach on record
- 3 Gm — Total length of "wiring" in the human brain.
- 4.2 Gm — Diameter of Algol B
- 5.0 Gm — Closest approach of Comet Halley to Earth, happened on 10 April 837
- 5.0 Gm — (proposed) Size of the arms of the giant triangle shaped Michelson interferometer of the Laser Interferometer Space Antenna (LISA) planned to start observations in or around 2015.
- 7.9 Gm — Diameter of Gamma Orionis
- 9.0 Gm — Estimated diameter of the event horizon of Sagittarius A*, the supermassive black hole in the center of the Milky Way galaxy
Distances longer than 10 metres
