On almost any clear night, dozens of satellites are passing silently overhead — and the brightest, like the International Space Station, are easy to spot with nothing but your eyes. You just have to know when and where to look. This guide explains what you can actually see, how to catch the ISS, and the simplest way to know what's overhead at a glance.
Can you really see satellites from your backyard?
Yes — and more than you'd think. Satellites don't produce their own light; you see them because they reflect sunlight back down to you. That's why the best viewing is in the couple of hours after sunset or before sunrise, when the sky above you is dark but a satellite high overhead is still catching the sun. To the eye, one looks like a steady star gliding smoothly across the sky in a straight line — no blinking, no flashing. If it has flashing lights, it's a plane.
What you can spot overhead
A few of the most rewarding targets:
- The International Space Station (ISS) — the brightest and best. It crosses the sky in a few minutes and can outshine almost everything up there.
- Starlink satellites — sometimes visible as a striking "train" of dots shortly after a launch, before they spread out into their orbits.
- Weather and Earth-observation satellites — like the long-running NOAA series in polar orbits.
- The Hubble Space Telescope — visible from lower latitudes under the right conditions.
- Spent rocket bodies and older satellites — fainter, but part of the fun of knowing what's passing.
How to see the ISS tonight
The ISS is the perfect first target because it's bright, fast, and predictable. Here's the simple version:
- Look in the hour or two after dark. That's when the station is still lit by the sun while you're in shadow.
- Know roughly when and where. A visible pass only lasts a few minutes, and the ISS rises from one horizon and sets at another, so you want a rough direction and time before you go out.
- Find an open patch of sky. Away from tall buildings and bright lights, with as wide a view of the horizon as you can get.
- Watch for steady, not blinking. A smooth, fast-moving "star" that doesn't flash is almost certainly the station.
The only hard part is the timing — passes change night to night, so you need something that tells you when the next good one is.
The easy way: SkyWatch Satellites mode
This is exactly what SkyWatch is built for. Its Satellites mode shows a sky dome — imagine lying back and looking straight up, with the centre directly overhead (the zenith) and the rim at the horizon. Satellites currently above your horizon appear as amber blips, using the same radar idiom as the rest of the device: a sweep arm, fading tracks and clear name tags.
Tap any satellite and you get who launched it and when, where it launched from, its COSPAR id, its orbit, its current range from you, and — most usefully — the time of its next visible pass, along with a photo. So instead of guessing, you can see at a glance that the ISS is coming over at, say, 9:14 tonight and step outside at the right moment.
Because it's computed for your exact home location and the current time, what you see on the dome matches what's actually above your roof.
More than satellites
The same round screen does far more than orbital tracking. Switch modes and SkyWatch becomes a live aircraft radar scope, a ship tracker over AIS, an offline planetarium of the bright stars and constellations, a weather radar, and more — so it's a window on the whole sky and sea, not a single-trick gadget. The night-sky modes work offline, and there's no subscription on the headline mode.
A few tips for better spotting
- Darker is better. Get away from direct light and give your eyes a few minutes to adjust.
- Check the weather. Even thin cloud hides a pass — a clear sky is everything.
- Start with the brightest. Nail an ISS pass first; the fainter satellites are easier once you know what motion to look for.
- Be patient at twilight. The richest viewing window is short, so be outside and looking up a couple of minutes early.
The bottom line
Satellite spotting is one of the most accessible bits of astronomy there is — no telescope, no dark-sky drive, just a clear evening and decent timing. The ISS alone is worth stepping outside for. And if you'd rather not wrestle with pass-prediction tables, SkyWatch shows you what's overhead right now and when the next good pass is coming — alongside planes, ships and the stars — all on one always-on screen.
