Hohmann Transfer Calculator

Calculate delta V for Hohmann transfer orbits between two circular orbits

📖 Hohmann Transfer

A Hohmann transfer is an elliptical orbit used to transfer a spacecraft between two circular orbits. It's the most fuel-efficient method for orbital transfers, requiring two engine burns.

📊 Result

💡 Tips & Information

Delta V is measured in meters per second (m/s)
Hohmann transfer requires two burns: one to enter transfer orbit, one to circularize
Total Δv = Δv₁ + Δv₂ (sum of both burns)
Transfer time = π × √((a³) / (GM)), where a is semi-major axis
Most efficient for transfers where final radius is less than 12x initial radius
