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
