STARLINK-5559 — Live Satellite Tracking (NORAD 56335)
Track STARLINK-5559 (NORAD catalog number 56335) 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 U of 2023's 58th orbital launch (COSPAR designation 2023-058U). It went up together with 43 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 18,560 revolutions of Earth.
Moving at about 7.63 km/s, STARLINK-5559 flies in low Earth orbit at an altitude of roughly 472 × 474 km, completing one revolution every 93.9 minutes — about 15.3 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0001). Its 97.3° retrograde, near-polar inclination is characteristic of a Sun-synchronous orbit — the type Earth-imaging and weather satellites use to revisit each spot at the same local solar time. Its orbital plane crosses the equator northbound at right ascension 247.2°. Earth's equatorial bulge precesses that plane eastward about 0.99° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

About the Starlink group
STARLINK-5559 is one of 10,717 SpaceX Starlink broadband satellites in the current WatchSat catalog — the largest satellite constellation ever flown. Starlink operates in low-Earth-orbit shells around 540–570 km. See the whole Starlink constellation move live in 3D.
Can you see STARLINK-5559 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-5559 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.
