Orbital Calculator 2.0.5 Released

Soyuz spacecraft New abilities include calculating Schwartzschild and Photon Sphere radii, and Synodic Periods of two orbiting objects based on either their distances from the host mass or their periods.

The photon sphere result assumes a non-rotating (Schwartzschild) black-hole. There is additional information about photon spheres around rotating black holes in the help file, although you should research what these are to get a more thorough understanding.

Synodic periods are important when using low-energy transfers from one orbit to another (which might equate to a transfer from one planet to another), where the timing of the arrival of both the target object and the spacecraft is important. The target object could be another planet, or a specific location in the geostationary orbit, and synodic periods dictate when such transfers can take place.
