Description

I just finished a fun Python-based comparative study of ‘Oumuamua, Borisov, and 3I/ATLAS using JPL Horizons data, 365 days before and after perihelion.

I basically pulled trajectory and photometric data from NASA’s JPL Horizons system and focused on a 730-day window around each object's perihelion, tracking their heliocentric velocity, distance from the Sun, and apparent magnitude. For 3I/ATLAS, the data is inferential since it hasn’t reached perihelion yet.

It took a few hours and a few hundreds lines of Python code to process and interpolate everything, but I learned a lot in the process and I'm pretty happy with how it turned out. Hopefully others will find it cool too!

Let me know if you're interested in seeing the code, happy to share 🤓👽🛰️
