To help compare different distances this page lists lengths starting at 1010 metres (10 gigametres (Gm) or 10 million kilometres, or 0.07 Astronomical units).
Distances shorter than 1010 metres
- 15 Gm — Closest distance of Comet Hyakutake from Earth
- 18 Gm — One light-minute (see yellow sphere in right-hand diagram)
- 24 Gm — Radius of a heliostationary orbit
- 46 Gm — Perihelion distance of Mercury (yellow ellipse on the right)
- 55 Gm — 60,000-year perigee of Mars (last achieved on August 27, 2003)
- 58 Gm — Average passing distance between Earth and Mars at the moment they overtake each other in their orbits
- 61 Gm — Diameter of Aldebaran, an orange giant star (large star on right)
- 70 Gm — Aphelion distance of Mercury
- 76 Gm — Neso's apocentric distance; greatest distance of a natural satellite from its parent planet (Neptune)
- 86 Gm — Diameter of Rigel, a blue supergiant star (largest star on right)
