Space Travel Time

Calculate travel time to planets and stars.

📜 The Origins

The universe is vast, and our current tech is slow. This tool uses real-world orbital mechanics and relativistic math to show you just how long it takes to reach our cosmic neighbors.

🚀 Master the Tool

Select your destination and your propulsion method (from chemical rockets to theoretical warp drives). We'll calculate the travel time for sowohl relative to Earth and the crew.

Mission Log:Hohmann orbital arcs are prioritized for Delta-V efficiency. Gates occur at optimal planetary conjunctions.
🌐 Orbital Arc

Gravity-assisted drifting between planetary spheres. High efficiency, low speed.

🎯 Launch Gate

Alignment-critical temporal window for mission start. Missing this gate causes indefinite stall.

⏳ Gate Lifecycle

The operational duration of the departure window. Fuel costs scale exponentially pre/post gate.

⚡ Brute Force

Direct High-Thrust trajectories ignoring orbital mechanics. Extreme energy cost.

Pro Tips

01Time dilation becomes significant as you approach light speed.
02The nearest star, Proxima Centauri, is 4.2 light-years away.
03Pack a very long book for chemical rocket trips.
