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.

NASA’s Double Asteroid Redirection Test Is a Smashing Success
Hi, I work on N-body orbit determination software for asteroid detection and planetary defense (for example, https://github.com/moeyensj/thor). Ask me anything.
You're right that orbit determination is unstable over long runs, and very sensitive to initial conditions. But the good news is that the solar system is big. Most trajectories do not intersect with the earth's location. So perturbing an orbit that we think has a small chance of hitting us tends to be safe.
Also, of course, after deflection, any object is going to be monitored really closely for a long time.

Building an E-Ink weather display for our home
Sweet, very nice.
I made a 'skyfield' widget for home assistant that shows the current position of the sun, moon and some planets as well as the summer and winter solstice paths. I really think it would be awesome for an e-ink display in the home. I've been planning to kick off that project at some point. This is inspiring.
