Data: the General Catalog of Artificial Space Objects (GCAT) by astrophysicist Jonathan McDowell, data update 24 Sep 2026, licensed CC-BY-4.0. It includes every catalogued object in Earth orbit since 1957: 69,761 objects, 33,858 still up. Counts were cross-checked against CelesTrak's copy of the U.S. Space Force catalogue and NASA's Orbital Debris Program Office.
Working vs dead: a satellite counts as working until GCAT's end-of-operations date. Rocket stages, components and fragments are dead from the start.
What is real on the globe: each object's height, orbit shape and tilt come from the catalogue. Where along its orbit it sits, and how its orbit is turned around the pole, are illustrative, because the catalogue does not record them. Heights are stretched so that low orbit is visible; the Orbits 101 panel shows the true scale.
The Space Station and Hubble are shown from their own orbits and are not in the count, because their catalogue histories continue outside the main catalogue.
Sketches are original line drawings, not to scale.
