Kilometres vs Distance
Fórmula
## 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
Ejemplo Resuelto
Proxima Centauri is about 4.246 ly away.
- 01km = 4.246 × 9 460 730 472 580.8
- 02≈ 4.017 × 10¹³ km
- 03AU = 4.246 × 63241 ≈ 268 521 AU
- 04pc = 4.246 / 3.2616 ≈ 1.302 pc
Preguntas Frecuentes
Is a light-year a unit of time or distance?
Distance. It measures how far light travels in one year.
Why do astronomers use parsecs too?
Parsecs arise naturally from the parallax method and are preferred in professional astronomy. 1 pc ≈ 3.262 ly.
How far is the nearest star?
Proxima Centauri: about 4.246 ly or 40.2 trillion km.
