 ====== Orbital Calculator 2.0.5 Released ======
 {{ :blog:articles:info:soyuz_tma-7_spacecraft2edit2.jpg?direct&400|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.
+**Synodic Periods, Schwartzschild and Photon Sphere radii**\\
+Calculate diameter of event horizons and photon spheres, also the synodic periods of planets (and other celestial bodies).
 === ===
 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.
