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.

Day 4: GitHub Actions for Colombian Spanish.
The first I encountered was GalSim. As it turned out the GitHub link included in the distribution was incorrect and that's why PyDigger reported it as having GitHub link but not CI on GitHub. So I sent a Pull-Request fixing that.
What are some alternatives?
pycbc - Core package to analyze gravitational-wave data, find signals, and study their parameters. This package was used in the first direct detection of gravitational waves (GW150914), and is used in the ongoing analysis of LIGO/Virgo data.

termtrack - Track satellites in your terminal
flask_fs_router - Straightforward file-based routing extension for Flask. Introduces the concepts of pages to Flask.
oorb - An open-source orbit-computation package for Solar System objects.
PyAutoLens - PyAutoLens: Open Source Strong Gravitational Lensing
astropy - Astronomy and astrophysics core library
sphinx-console - A sphinx extention that can render command in console style.
