Open calculatorEscape Velocity Calculator is an educational astronomy tool for exploring a standard quantitative relationship.
Enter the requested values using the stated units. The calculator validates the numerical domain and applies vₑ = 11.186 × √(M/R) km/s.
Variables: M = Mass (Earth masses); R = Radius (Earth radii).
Example: M = 1 Earth mass, R = 1 Earth radius → vₑ = 11.186 km/s.
It is intended for astronomy study, classroom exercises and understanding the quantitative relationship represented by the model.
No. Astronomy formulas often rely on simplifying assumptions, approximations or specific unit conventions. Interpret the result within the stated model.
