About
The sky is infrastructure. It is also cluttered.
Unseen Orbits shows the satellites and tracked space debris above any place on Earth, explains what each object is, and helps you understand the active machinery and abandoned hardware moving overhead.
Two kinds of objects, equal weight
The sky above you holds active machines — communication, navigation, imaging, science, weather, and human spaceflight — and leftovers: inactive satellites, rocket bodies, and fragments. Most tools focus on the romantic side. We give satellites and tracked debris equal footing, because both are really up there.
Calm, not alarmist
Space debris is real, but it is not “danger overhead.” We use plain, sober language — rocket body, inactive payload, fragment, tracked object — and frame debris as orbital history and shared environment, not a threat to your city. The goal is curiosity, not fear.
Honest about limits
We track publicly cataloged objects — a few thousand of them — not all debris. Most debris is too small to track individually. Predictions are estimates that drift as data ages. “Above your horizon” is not the same as “visible.” We would rather tell you what we don’t know than overclaim. See Data & calculations.
This is not a weather app
It is an orbital object tracker. No clouds, no forecast — just what is moving through space above your location, and why it matters.
