No. One AU is the mean Earth–Sun distance. A light‑year is the distance light travels in one Julian year. 1 light‑year ≈ 63,241.077 AU.
1 AU = 149,597,870,700 meters (IAU 2012). That equals 149,597,870.7 km.
About light‑minutes; light needs roughly eight minutes to reach Earth from the Sun.
≈ miles.
1 parsec ≈ 206,264.806 AU. It’s based on a parallax of one arcsecond from Earth’s orbit radius.
We compute from SI definitions: exact AU in meters and exact speed of light. Rounding shown for readability.
