Как да изчислим Astronomy Space
Какво е Astronomy Space?
Astronomy and space calculators convert observations into physical quantities — apparent and absolute magnitudes, stellar luminosity, redshift, and orbital parameters. They bridge telescope readings and astrophysical reality.

- 1Magnitude: m − M = 5 log₁₀(d) − 5 (distance modulus)
- 2Luminosity: L/L☉ = (R/R☉)² × (T/T☉)⁴ (Stefan-Boltzmann)
- 3Redshift: z = (λ_obs − λ_emit) / λ_emit
Worked Examples
Вход
Star at 100 pc · absolute magnitude M = 4.8
Резултат
Apparent magnitude m = 9.8
5 log(100) − 5 = 5, so m = M + 5 = 9.8
