From the README

** ACCESS THE LIVE ENGINE **

Keplerian Module è un'architettura di simulazione astrofisica bidimensionale sviluppata per il calcolo in tempo reale del problema degli $N$-corpi (N-Body problem). A differenza dei modelli cinematici basati su orbite pre-calcolate, questo motore risolve dinamicamente le interazioni gravitazionali tra entità celesti, elaborando la propagazione spaziale frame per frame attraverso l'integrazione numerica delle forze.

Il progetto unisce la computazione fisica rigorosa a un'interfaccia utente (HUD) di ispirazione hardware industriale.
