COSMOS 1989 (ETALON 1) — Live Satellite Tracking (NORAD 19751)
Track COSMOS 1989 (ETALON 1) (NORAD catalog number 19751) 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 C of 1989's 1st orbital launch (COSPAR designation 1989-001C). As of this element set it had completed roughly 29,311 revolutions of Earth.
Moving at about 3.96 km/s, COSMOS 1989 (ETALON 1) operates in medium Earth orbit at roughly 19,073–19,192 km altitude, taking about 11.3 hours per revolution (2.13 orbits a day). The orbit is essentially circular (eccentricity 0.0023). Inclined 65.0° to the equator, it overflies every latitude up to about 65° north and south. Its orbital plane crosses the equator northbound at right ascension 69.4°.

Can you see COSMOS 1989 (ETALON 1) from the ground?
Not with the naked eye. At its altitude COSMOS 1989 (ETALON 1) 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.
