Passes over you
Say where you are and your own next passes appear here, the first drawn across your sky.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
Meanwhile, the next visible pass over three cities:
- LondonNo visible pass in the next 10 days
- New York CityNo visible pass in the next 10 days
- SydneyNo visible pass in the next 10 days
How to see it
It crosses the sky as a steady point of light, no brighter than a faint star, a few minutes from one horizon to the other and never blinking. Its orbit keeps it over the line between day and night, so the hour after sunset and the hour before sunrise are the times to look, under as dark a sky as you can find. It can be seen from anywhere on Earth.
Passes over: Dublin, Istanbul, Kolkata, Jakarta, Perth, Seattle, Bogotá, Cairo, every city
Altitude
One reading a day, worked out from the elements Space-Track publishes.

Summary
Over the Pacific Ocean LIVE
Where is Suomi NPP?
At 3:04:06 AM UTC Suomi NPP was over the Pacific Ocean (7.4° N, 157.6° E), 829 km up, moving at 7.44 km/s and in sunlight.
What is Suomi NPP?
A satellite that watches the Earth in low Earth orbit, in space since Oct 28, 2011.
Can I see Suomi NPP tonight?
Yes: Suomi NPP can be seen with the naked eye when it passes over you in a dark sky, after dusk or before dawn, as a steady light that crosses the sky in a few minutes.

No operator publishes an ephemeris for Suomi NPP, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Suomi NPP has been reported publicly in the past thirty days.
- Losing to drag
- Suomi NPP is falling less than a metre a day, read from the last 48 days of samples.
From Space-Track’s public conjunction messages; the latest report was issued Nov 2, 2026, 1:53 PM, 13 hours old. Only approaches serious enough to be reported publicly are listed: within three days and, for two bodies near the Earth, closer than a kilometre with a chance of a collision above 1 in 10,000, the level at which NASA moves the ISS.
