The current public orbital catalog identifies this object, but verified mission-specific information may be limited. TransitSatellite will expand this page when authoritative information is available.

The current two-line element set reports approximately 12.1234 revolutions per day. Dividing 1,440 minutes by that value gives an estimated orbital period of 118.8 minutes.

The orbital catalog lists the launch designator as 1991-086A. A fully sourced launch story, launch vehicle, deployment sequence, historical weather, and documented delays have not yet been added to this page.

Low Earth orbit is the region closest to Earth used by most crewed spacecraft, many science missions, Earth-observation satellites, and large constellations. Objects move quickly and commonly complete an orbit in roughly 90 to 130 minutes.

LEO can provide detailed Earth views, lower communications delay, and easier access than higher orbits, but it covers less area per spacecraft and is more affected by atmospheric drag.

• What can an orbit tell us before the mission is fully identified?
• Why are stable catalog identifiers important?

Current identity and orbital elements come from CelesTrak’s public GP data. Calculated orbit values are derived from the current TLE and may change after catalog updates. Mission-history claims are added separately and require authoritative sources.
