The local space context of Yantai as this registry holds it — the catalogued
human footprint on the ground around it, the orbits that can pass overhead, and the geostationary belt
seen from here.

Distances are great-circle on a sphere of mean radius 6,371 km; bearings are initial true
bearings from the city. Each position is the source catalogue's own, read back from the registry.
What can pass overhead
Of the 23,251 artificial objects the registry places in Earth orbit
on 2026-10-18, 20,017 fly orbits whose ground
track reaches 37.477° N, so they can pass directly overhead; the other
3,234 never reach this latitude.
Computed: an orbit's equatorial inclination bounds the latitudes its track reaches (inclination
i, or 180° − i when retrograde), from the orbital elements the registry holds. «Can pass overhead» is
geometry, not a schedule — when, and whether it is lit and visible, depends on the hour.
The geostationary belt from here
The geostationary belt arcs across the southern sky and stands
46.6° above the horizon due south — the
elevation to aim at for a satellite at this city's own longitude. Computed: spherical Earth
(equatorial radius 6,378.137 km), circular orbit of one sidereal day (42,164 km); good to a few tenths of a
degree.
What this page does not know
Tonight's sky and pass times. They depend on the hour, so a static page would print a
stale number. Open the live scene in a browser: /sim.html#sel=EARTH&tn=1,
then stand at Yantai in Stargazing — it computes which satellites are visible now, from this
registry, in your browser.
Anything not catalogued. A site absent from the source catalogues is absent here; an
empty list means «not in the registry», not «nothing there».
Precision beyond the sources. Positions carry the precision their catalogue published.
