1 gigametre

Template:Associations/Orders of magnitude (length) To help compare different distances this page lists lengths starting at 10⁹ m (1 Gm or 1 million km).

Distances shorter than 10⁹ m

• 1,400,000 km — Diameter of Sun
• 1,500,000 km — Expected orbit from Earth of the James Webb Space Telescope
• 2,190,000 km — Closest approach of Comet Lexell to Earth, happened on July 1, 1770; closest comet approach on record
• 4,200,000 km — Diameter of Algol B
• 5,000,000 km — Closest approach of Comet Halley to Earth, happened on April 10, 837
• 7,900,000 km — Diameter of Gamma Orionis
• 9,000,000 km — Estimated diameter of Sagittarius A*, the supermassive black hole in the center of the Milky Way galaxy
