## Light-Year Conversion

A light-year is the distance light travels in one Julian year (365.25 days).

**1 ly = 9 460 730 472 580.8 km**

From: c × t = 299 792.458 km/s × 31 557 600 s

Lösungsbeispiel

Proxima Centauri is about 4.246 ly away.

  1. km = 4.246 × 9 460 730 472 580.8
  2. ≈ 4.017 × 10¹³ km
  3. AU = 4.246 × 63241 ≈ 268 521 AU
  4. pc = 4.246 / 3.2616 ≈ 1.302 pc
