Interplanetary Flyby
Visualize a gravitational assist using a planar hyperbolic flyby.

Relativistic Flight Profile
Constant proper acceleration (half-way turn-around) with accel → cruise → decel if distance allows.
Use the arrow controls or type new values. The plot and legend update automatically with no extra button clicks.
Warp Reference (1 ly trip)
Each warp factor W corresponds to a relativistic speed where the traveler’s time is 1/W of photon time for a 1 ly journey. Distances are the traveler’s effective distance (length contraction).
Relativistic Starfield
Click the starfield once to focus, then use keys:
Simulation
Changing this regenerates the star bubble.
This is “per second”; the sim scales it by frame dt.
90° is a nice default. Ring shrinks with speed.
Example: 10 means 0.01c = 0.1 ly/s (1 ly per 10 s).
