Light-Years vs Distance
Formel
## Parsec Conversion **1 pc = 206 265 AU ≈ 3.2616 ly ≈ 3.0857 × 10¹³ km** Parsecs are the natural unit in stellar astronomy because they link directly to parallax measurement.
Lösungsbeispiel
Sirius is about 2.64 parsecs away.
- 01ly = 2.64 × 3.26156 = 8.610 ly
- 02AU = 2.64 × 206265 = 544 539 AU
- 03km = 2.64 × 3.0857e13 ≈ 8.146e13 km
Häufig Gestellte Fragen
Why parsecs over light-years in research?
Parsecs tie directly to parallax angles (d = 1/p), simplifying calculations.
What are kpc and Mpc?
Kiloparsec (1000 pc) for galactic scales. Megaparsec (10^6 pc) for cosmological distances.
How big is one parsec?
About 3.26 light-years. The Milky Way is roughly 30 kpc across.
