Where the Space Station is
Loading the latest orbit…
Set a location to find out if you can see anything tonight.
What’s passing over you
See the next bright things crossing your night sky
We’ll use your location only in this browser to figure out when the Space Station, China’s Tiangong station, Hubble, and freshly launched Starlink trains pass over you — and which way to look.
Your location stays on your device. We never receive it.
Overhead right now
Where the Space Station is on Earth this moment — live ground track, day/night line, and speed. Works even before you set a location.
A one-page handout for tonight — big type, for printing or saving as a PDF.
Worked out in your browser for your location — no extra weather or astronomy service.
Set a location to see the moon, visible planets, and upcoming meteor showers.
A plain-language timeline for the night you pick — trains, bright passes, moon, planets, and meteor peaks. All worked out on your device.
Set a location to build your night timeline.
When the Space Station appears to skim or cross the Moon or Sun from your place — rare, brief, and worth planning for.
Never look at the Sun without a proper solar filter.
Do not use sunglasses, smoked glass, or an unfiltered camera, binoculars, or telescope. A solar transit is only safe through a certified solar filter on the front of the instrument — or by projecting the Sun onto a card. Lunar crossings need no filter.
Set a location to check for Moon and Sun approaches.
A live all-sky view of what’s above you right now, plus how many Starlink satellites are in view.
The sky above you
North is at the top. Tap a dot to see its name, how high it is, and which way to look.
Tap a dot to see what it is.
Bright dots are in sunlight. Dim dots are in Earth’s shadow. Small teal dots are Starlink.
Phone sky view — point your device; no camera. Works best outdoors.
Plane or satellite? Planes usually blink and show red or green lights, and they cross the sky faster. Satellites are a steady white light that glides, and they can fade out when they slip into Earth’s shadow.
We don’t draw airplanes on this map. The free aircraft feeds we checked either don’t allow use on a public website, or can’t be read from your browser without us seeing your location.
Starlink above the horizon

Set a location to count how many Starlink satellites are above your horizon right now.
Next visible pass
The next one worth stepping outside for — countdown, which way to look, and whether clouds will cooperate.
We’ll remind you before a pass, on this device only. Permission is asked only when you tap.
On iPhone and iPad Safari, add this page to your Home Screen first (Share → Add to Home Screen), then open it from there so alerts can appear.
One note each evening if the sky looks clear enough. It only works while this page stays open or you’ve added it to your Home Screen — we can’t ping you after the tab is closed.
Set a location to see your next pass.
Only the ones you can actually see: the satellite is in sunlight, you’re in darkness, and it climbs at least 10° above the horizon.
