100 gigametres

100 gigametres
From largest to smallest: Jupiter's orbit, red supergiant star Betelgeuse, Mars' orbit, Earth's orbit, star R Doradus, and orbits of Venus, Mercury. Inside R Doradus' depiction are the blue giant star Rigel and red giant star Aldebaran. The faint yellow glow around the Sun represents one light minute.

To help compare distances at different orders of magnitude this page lists lengths starting at 1011 metres (100 Gm or 100 million kilometres or 0.7 astronomical units).

Distances shorter than 1011 m

  • 109 Gm — 0.7 AU — Distance between Venus and the Sun
  • 149.6 Gm (93.0 million mi) — 1.0 AU — Distance between the Earth and the Sun - the definition of the astronomical unit
  • 180 Gm — 1.2 AU — Maximum diameter of Sagittarius A*, the supermassive black hole in the center of Milky Way galaxy
  • 228 Gm — 1.5 AU — Distance between Mars and the Sun
  • 570 Gm — 3.8 AU — Length of the tail of Comet Hyakutake measured by Ulysses; the actual value could be much higher
  • 591 Gm — 4.0 AU — Minimum distance between the Earth and Jupiter
  • 624 Gm — 4.2 AU — Diameter of Antares
  • 780 Gm — 5.2 AU — Distance between Jupiter and the Sun
  • 965 Gm — 6.4 AU — Maximum distance between the Earth and Jupiter
