   We got enough data to get a rough estimate of its orbit before it hit: https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?sstr=2024%... Note though, this will likely have a huge range of uncertainty on it, as 8 hou

   I am in the rather lengthy process of open sourcing a library for orbit propagation, but the previous art which is somewhat modern is the python rebound package. It's original design intent was for asteroid collision simulations, but i

   The range of mass is typically much larger than the range of velocities. There is an upper bound to the speed for the vast majority of things which are dangerous (escape velocity of the solar system). However there are orders of magnitude d

   I work on the NASA NEO Surveyor project (and have helped out a lot on the WISE/NEOWISE mission, which found a lot of asteroids). I create and run simulations of asteroid detections, which ends up being mostly orbit calculations. In the
