Astronomical converters translate between au (astronomical units), light-years, parsecs, and kilometers for cosmic distance measurements.
Guida passo passo
- 11 AU = 149.6 million km (Earth-Sun distance)
- 21 light-year ≈ 9.46 trillion km (distance light travels in 1 year)
- 31 parsec ≈ 3.26 light-years (parallax-based unit)
Esempi risolti
Ingresso

Risultato
63,241 AU, 0.307 parsecs, 9.46 trillion km
Cosmic scale perspective
Errori comuni da evitare
- ✕Confusing distance units with time (light-year is distance, not time)
- ✕Not appreciating cosmic scale (numbers become abstract)
Domande frequenti
Why use light-years?
Human-scale understanding: distance light travels in time we understand (years).
Is parsec still used?
Yes, in astronomy literature. Based on stellar parallax measurements; convenient for stellar distances.
