CXO — Live Satellite Tracking (NORAD 25867)
Track CXO (NORAD catalog number 25867) live on the WatchSat interactive 3D globe above. Its position is propagated in real time from the latest CelesTrak two-line element set using the SGP4/SDP4 orbital model — the same math professional trackers run. It is object B of 1999's 40th orbital launch (COSPAR designation 1999-040B). As of this element set it had completed roughly 1,763 revolutions of Earth.
Its speed swings from 0.80 km/s at apogee to 6.18 km/s at perigee. CXO follows a highly elliptical orbit, completing a revolution every 63.5 hours. The orbit is strongly elliptical (eccentricity 0.7710): each revolution swings from 12,134 km at perigee out to 136,703 km at apogee. Inclined 57.4° to the equator, it overflies every latitude up to about 57° north and south. Its orbital plane crosses the equator northbound at right ascension 114.4°.

This page's orbital elements come from the CelesTrak catalog of 2026-09-08. The live 3D view above fetches its own current CelesTrak data when the page opens, through an edge cache that refreshes roughly every 30 minutes.
About the Other Active Satellites group
CXO is one of 4,471 active satellites in WatchSat's general catalog — the broad population of Earth-observation, communications, science, amateur-radio and technology spacecraft outside the giant broadband constellations. Browse all other active satellites live in 3D.
Can you see CXO from the ground?
Not with the naked eye. At its altitude CXO is far beyond unaided visibility — following satellites this high takes a telescope and good timing. You can still track it precisely in the live 3D view above, or check pass predictions for your location.
