# OrbitalNodes.ai

> A live satellite tracker. It shows which satellites — the ISS, Starlink trains, Tiangong, Hubble and thousands of others — are passing over a visitor's exact location right now, with plain-English directions. It also publishes live daily counts of everything in Earth orbit, sourced from the US Space Command (Space-Track.org) catalogue. Live figures on these pages are rendered into the raw HTML (not JavaScript) and refresh daily; per-city pass times are recomputed every night from current orbital elements.

## Live space data
- [The State of Orbit](https://orbitalnodes.ai/state-of-orbit/): Live daily count of everything in Earth orbit — total tracked objects, satellites, rocket bodies, debris, every mega-constellation, people in space, and the catalogue milestone. The single best page for "how many ___ are in orbit right now".
- [Satellites in Orbit](https://orbitalnodes.ai/satellites-in-orbit/): How many tracked objects orbit Earth right now, broken down by country.
- [Satellite Catalogue Numbers](https://orbitalnodes.ai/satellite-catalog-numbers/): The catalogue passed its five-digit limit in 2026; live highest catalogue number and count of six-digit objects.

## Trackers

- [Tiangong](https://orbitalnodes.ai/tiangong/): China's space station — next visible pass.
- [Hubble](https://orbitalnodes.ai/hubble/): Hubble Space Telescope passes.
- [Reentry Tracker](https://orbitalnodes.ai/reentry/): Next predicted satellite reentry, with size, origin, debris risk, and a live ground track.

## Mega-constellations (live counts)
- [Starlink](https://orbitalnodes.ai/starlink/): SpaceX Starlink — live in-orbit count and visible passes.
- [Amazon Leo (Kuiper)](https://orbitalnodes.ai/kuiper/): Amazon's satellite-internet constellation — live count, scaling toward 3,236.
- [OneWeb](https://orbitalnodes.ai/oneweb/): OneWeb — live count, near-polar orbit at 1,200 km.
- [Qianfan](https://orbitalnodes.ai/qianfan/): Qianfan / Thousand Sails, China's Starlink rival — live count.
- [Guowang](https://orbitalnodes.ai/guowang/): Guowang, China's state megaconstellation — live count.
- [BlueBird](https://orbitalnodes.ai/bluebird/): AST SpaceMobile BlueBird — direct-to-phone satellites, among the brightest in orbit.

## Compare constellations
- [Constellations Compared](https://orbitalnodes.ai/compare/): Every major constellation side by side with live in-orbit counts — Starlink, Amazon Leo (Kuiper), OneWeb, Qianfan, Guowang and BlueBird — with planned totals, altitude, inclination, operator country and service status. The best page for "which constellation is biggest" or "Starlink vs Amazon Leo".

## Pass times by city (recomputed nightly)
- [All cities](https://orbitalnodes.ai/cities/): 113 city pages. Each answers "can I see satellites from <city> tonight" with the number of visible passes, the best pass and its peak elevation, and the dark-sky viewing window — all in that city's own timezone, recomputed each night.
- Examples: [London](https://orbitalnodes.ai/london/), [New York](https://orbitalnodes.ai/new-york/), [Sydney](https://orbitalnodes.ai/sydney/), [Cape Town](https://orbitalnodes.ai/cape-town/), [Berlin](https://orbitalnodes.ai/berlin/), [Delhi](https://orbitalnodes.ai/delhi/).

## Identify what you saw
- [Satellite or Plane?](https://orbitalnodes.ai/satellite-vs-plane/): How to tell a satellite from an aircraft. The short answer: satellites do not blink. A steady, silent light gliding smoothly across the sky is a satellite; flashing red and white lights are a plane.
- [Identify That Light](https://orbitalnodes.ai/identify/): Answer when you saw it, which direction and what it looked like, and get the most likely match from over 400 tracked satellites.
- [Satellite Brightness Guide](https://orbitalnodes.ai/satellite-brightness/): How bright satellites actually get, on the magnitude scale. The ISS reaches magnitude -5.9, brighter than Venus; Starlinks are magnitude 3 to 6.
- [Satellite Trails in Astrophotography](https://orbitalnodes.ai/satellite-trails/): Why satellites streak long exposures, and the window each night when fewest are sunlit.

## Planning and conditions
- [Pass Guide](https://orbitalnodes.ai/passes/): How satellite passes are predicted, and the next visible pass over your location.
- [Tonight](https://orbitalnodes.ai/tonight/): What is visible from your location tonight, with a viewing verdict from cloud cover and moon phase.
- [How to Spot Satellites](https://orbitalnodes.ai/learn/): No telescope needed. If you can see stars, you can see satellites.
- [Solar Weather](https://orbitalnodes.ai/solar-weather/): Live Kp index, geomagnetic conditions and aurora likelihood.
- [Meteor Showers](https://orbitalnodes.ai/meteor-showers/): The next shower, its peak date and expected rate.
- [Dark Sky Sites](https://orbitalnodes.ai/dark-sky/): 25 named dark-sky sites worldwide, each with its Bortle class and what that makes visible.
- [Launch Sites](https://orbitalnodes.ai/launch-sites/): Every active orbital launch site, its cadence, and which orbits it can reach.
- [Launch Schedule](https://orbitalnodes.ai/launches/): Upcoming orbital launches and which are visible from the ground.

## Satellite internet coverage
