Loading orbital elements…
ISS pass times tonight and over the following days from your location, live position and ground track, for the station and any satellite in the CelesTrak catalogue.
Past orbit Next orbit Area where the object is visible Night
Passes over the next 10 days
| Day | Start | Duration | Max altitude | Path | Brightness |
|---|
Visible = object lit by the Sun, more than 10° above the horizon, at night (Sun more than 6° below the horizon). Brightness in magnitude: the lower the number, the brighter the object (Venus: −4).

Bright satellites tonight

| Start | Object | Max altitude | Path | Duration |

The roughly 150 brightest objects in orbit, per CelesTrak: satellites, and many spent rocket stages, often brighter. Passes above 20°, at night, with the object lit by the Sun. Click a row to follow it on the map.

About this tool
What it does
It shows where the ISS, or any other satellite, is on a world map with its ground track, and computes its visible passes from your location over the next 10 days, ready to add to your calendar. It also lists the bright satellites passing over the next 18 hours.
The calculations
Positions computed on your device by satellite.js (SGP4 model) from the orbital elements. A pass is visible when the satellite is sunlit, more than 10° high, in a dark enough sky (Sun more than 6° below the horizon). Brightness estimated with the Heavens-Above method. Featured pass: the first in the next 3 days reaching at least 40° or magnitude −2 or brighter (preferably −3 or brighter), otherwise the next visible pass.
The sources
Orbital elements from CelesTrak, updated several times a day, relayed by adastrum.fr so as not to overload the service. Map: Natural Earth, public domain. Your location is never sent to any server.
How to see the ISS tonight?
Look at the highlighted pass at the top of the page: start time, the direction it appears from and its maximum altitude. To the naked eye it is a bright dot crossing the sky without blinking. Also check tonight's clouds on tonight's sky.
Why no pass tonight?
The ISS can only be seen when it is lit by the Sun while your sky is dark, so usually early or late in the night. Depending on the season and its orbit, several days can go by without a visible pass: the list covers the next 10 days.
Which other satellites can I see?
The bright satellites list gives, for the next 18 hours, the passes above 20° of the roughly 150 brightest objects tracked by CelesTrak, many of them rocket stages.
