Astronomical Unit Umrechner — Formel

## The Astronomical Unit

**1 AU = 149 597 870.7 km (exact, IAU 2012)**

Light takes about 8.317 minutes to travel 1 AU. The AU is the fundamental baseline for solar system distances.

Lösungsbeispiel

Jupiter orbits at about 5.2 AU.

  1. km = 5.2 × 149 597 870.7 ≈ 778 million km
  2. Light-minutes = 5.2 × 8.317 = 43.2
  3. Light takes about 43 minutes to reach Jupiter from the Sun.
