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〔Richichi, A.; Roccatagliata, V. (Aldebaran's angular diameter: How well do we know it?. ) Astronomy and Astrophysics, Volume 433, Issue 1, April I 2005, pp.305-312. "We derive an average value of 19.96±0.03 milliarcsec for the uniform disk diameter. The corresponding limb-darkened value is 20.58±0.03 milliarcsec, or 44.2±0.9 Rȯ."〕〔Richichi, A. and Roccatagliata, V. derived an angular diameter of 20.58±0.03 milliarcsec, which given a distance of 65 light years yields a diameter of 61 million km〕 — 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) Distances longer than 1011 metres ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「10 gigametres」の詳細全文を読む スポンサード リンク
