Astronomy

Escape Velocity Calculator

Find the minimum speed an object must reach to escape a celestial body's gravity without further propulsion. Essential for mission planning, planetary science, and understanding why some atmospheres are retained.

Astronomy

Distance Modulus Calculator

Compute distance to a celestial object in parsecs from its apparent and absolute magnitudes using the distance modulus formula d = 10^((m − M + 5)/5). The standard "standard candle" technique for measuring distances across the Milky Way and to nearby galaxies.
