Learn the basics

Right now there are thousands of working satellites circling Earth, plus tens of thousands of tracked pieces of debris. Each one follows a predictable orbit, so if you know where it is and how fast it’s moving you can calculate exactly where it will be minutes or days from now — and whether it will fly over your backyard tonight.

OrbitLive takes the public catalog of orbital data — Two-Line Element sets, or TLEs, published by CelesTrak — and propagates each object forward with the standard SGP4 model to compute its live position and ground track. The result is a real-time map of the sky overhead, the International Space Station included, with pass predictions for your location.

Orbits explained: LEO, MEO and GEOWhy altitude sets a satellite’s speed and job — from the low, fast orbits of the ISS and Starlink to the parked-in-place geostationary belt.The International Space StationWhat the ISS is, how fast and how high it flies, who lives aboard, and why it’s the easiest spacecraft to spot with the naked eye.How to spot satellites and the ISSThe dawn-and-dusk trick that makes satellites visible, what a “pass” is, how to read magnitude, and how to tell a satellite from a plane.Space debris and orbital trafficOrbital decay and reentry, the growing cloud of debris, the Kessler-syndrome risk of cascading collisions, and crowding from megaconstellations.
