Astrophyzix CNEO Observatory

This module visualizes and tracks detected Near‑Earth Objects (NEOs) using current data, allowing users to explore orbital parameters, close approach distances, and potential Earth interaction. (View CNEO Observatory)

Scientific Basis

The CNEO Observatory integrates current orbital data of Near‑Earth Objects to illustrate real astrophysical behavior of minor bodies in the solar system. It applies Keplerian orbital mechanics and two‑body gravity approximations to compute orbital positions and close‑approach geometry. NEO tracking is grounded in observational astronomy using astrometry collected from surveys like Pan‑STARRS, Catalina Sky Survey, and validated by the Minor Planet Center and NASA’s Center for Near Earth Object Studies (CNEOS).

Key Equations

Orbital period (Kepler’s 3rd Law):
P = 2π √(a³ / μ)
where a is semi‑major axis and μ = GM (standard gravitational parameter).

Vis‑Viva Equation:
v = √(μ (2/r − 1/a))
describes orbital speed as a function of distance r and semi‑major axis a.

Minimum orbit intersection distance (MOID):
A computed scalar indicating the smallest distance between the NEO orbit and Earth’s orbit—used in risk evaluation.
