WebDec 20, 2024 · The average distance from the Earth to the Sun is defined as 1 Astronomical Unit (AU), so the ratio table gives this distance in AU. * For the Moon, the average distance from the Earth is given. Perihelion, Aphelion (10 6 km or 10 6 miles) - The closest and furthest points in a planet's orbit about the Sun, see "Distance from Sun" above. WebIn the IERS numerical standards, the speed of light in a vacuum is defined as c 0 = 299 792 458 m/s, in accordance with the SI units. The time to cover an AU is τ A = 499.004 783 8061 ± 0.000 000 01 s, resulting in the astronomical unit in metres as c 0 τ A = 149 597 870 700 ± 3 m.
