Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Calculating delta-v for biome hopping
I found the optimal delta-v using a lambert solver (my favorite is Izzo's 2015 method, an implementation of which can be found here) to get the launch delta-v and landing delta-v (as vectors) after inputting the initial location, final location, and time of flight. To get the best delta-v, I just used a Nelder-Meade method from scipy.optimize.minimize to vary the time of flight until the magnitude of launch & landing delta-v was minimized. I actually am not sure whether there's a purely analytical method of finding the optimal angle, though I wouldn't be surprised if there is. If you do want to try an analytical approach, you might look into the Lagrange f & g series orbital solutions.
