Astronomical Calculators — Unit Conversion
Astronomical distance and motion: parsecs to light years, escape velocity, orbital speed, gravitational force, and astronomical time units. Escape velocity depends only on mass and radius, which is why small dense bodies can be harder to leave than large diffuse ones.

About Astronomical & Space Calculators
Astronomical distance and motion: parsecs to light years, escape velocity, orbital speed, gravitational force, and astronomical time units. Escape velocity depends only on mass and radius, which is why small dense bodies can be harder to leave than large diffuse ones.
Whether you need to solve a one-time problem or verify your own calculations, these free tools cover the most common astronomical & space scenarios. All results are computed in your browser — no data is sent to any server.
