Schwarzschild Radius Calculator
Schwarzschild Radius Calculator finds a black hole’s event horizon from planet/star masses, with a plot.
Formulas Used in Schwarzschild Radius Calculator
The calculator computes the Schwarzschild radius of a non-rotating black hole:
Schwarzschild Radius:
\\[ r_s = \frac{2 G M}{c^2} \\]Where:
- \\(r_s\\): Schwarzschild radius (m)
- \\(G\\): Gravitational constant (\\(6.67430 \times 10^{-11} \, \text{m}^3 \text{kg}^{-1} \text{s}^{-2}\\))
- \\(M\\): Mass of the object (kg)
- \\(c\\): Speed of light (\\(2.99792458 \times 10^8 \, \text{m/s}\\))
Example Calculation
Example: \\(M = 1.989 \times 10^{30} \, \text{kg} (Sun)\\)
\\[
r_s = \frac{2 \times 6.67430 \times 10^{-11} \times 1.989 \times 10^{30}}{(2.99792458 \times 10^8)^2} \approx 2953.25 \, \text{m}
