BB 2 — Live Satellite Tracking (NORAD 56170)
Track BB 2 (NORAD catalog number 56170) 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 J of 2023's 50th orbital launch (COSPAR designation 2023-050J). It went up together with 9 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 17,285 revolutions of Earth.
Moving at about 7.48 km/s, BB 2 flies in low Earth orbit at an altitude of roughly 767 × 780 km, completing one revolution every 100.2 minutes — about 14.4 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0009). Inclined 81.0° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 357.6°. Earth's equatorial bulge drifts that plane westward about 1.05° per day.

About the Other Active Satellites group
BB 2 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 BB 2 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, BB 2 is visible only around dawn and dusk, when your sky is dark but the satellite is still sunlit — and whether you can spot it depends on its size and reflectivity. See pass predictions for your location for when it is above your horizon and sunlit.
