Current orbit
View on live mapOne orbit takes a day, as long as the Earth takes to turn, so Hermes keeps above 143.3° W of the equator and never crosses the sky.
It never rises or sets
Hermes turns with the Earth, standing over one longitude of the equator. From anywhere it can be seen at all it is up day and night, in the same direction, so there is no pass to wait for.
No brightness has been published for Hermes, so it is not a naked-eye satellite and no city page carries pass times for it. Nothing here estimates one.
Seeing it
There is nothing to wait for: it never crosses the sky. From the half of the Earth it stands over it keeps the same point day and night, and from the other half it never rises at all.

Summary
Over the Pacific Ocean LIVE
Where is Hermes?
At 5:36:12 PM UTC Hermes was over the Pacific Ocean (3.5° S, 143.3° W), 35,732 km up, standing over one longitude of the equator and in sunlight.
What is Hermes?
A communications satellite in geostationary orbit, in space since Jan 17, 1976.
Can I see Hermes?
No, not with the naked eye, and it never crosses the sky: Hermes stands over 143.3° W of the equator; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Hermes, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Hermes has been reported publicly in the past thirty days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 8, 2026, 1:11 PM, 3 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.
