CAPELLA-11 (ACADIA)

CAPELLA-11 (ACADIA) is an active satellite operated by Capella Space (United States), launched on 2023-08-23 from RLLC. It orbits in Low Earth Orbit (LEO) at altitudes between 617 km and 619 km with an inclination of 53.0°. It travels at approximately 27,187 km/h (7.55 km/s), completing one full orbit every 97 minutes — that’s roughly 14.84 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~10–25 years. Orbital Radar tracks CAPELLA-11 (ACADIA) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

CAPELLA-11 (ACADIA) orbits at an average altitude of 618 km in the mid-LEO band, where atmospheric drag is minimal but radiation exposure remains manageable. Objects at this altitude persist for decades to centuries, making debris mitigation critical. This regime is popular for remote sensing constellations and scientific instruments that need stable, long-duration orbits. Within ±50 km of CAPELLA-11 (ACADIA)’s average altitude, there are currently 1,547 active payloads and 748 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3090, STARLINK-3077. This makes it one of the more crowded altitude bands, containing roughly 8.9% of all active satellites. With an inclination of 53.0°, CAPELLA-11 (ACADIA) passes over latitudes between 53.0°N and 53.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 12,339 active satellites in total, of which 1,059 share a similar altitude band with CAPELLA-11 (ACADIA).
