In view from you
Nobody watches Kosmos-546 go over, but a receiver still asks whether it is above the horizon. Say where you are and this card answers.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
No brightness has been published for Kosmos-546, 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 go outside for: it is far too high and too faint for the naked eye. What you notice of it is a position fix, and the card above says whether it is above your horizon to give you one.

Summary
Over the Pacific Ocean LIVE
Where is Kosmos-546?
At 7:07:46 AM UTC Kosmos-546 was over the Pacific Ocean (28.9° N, 166.8° E), 465 km up, moving at 7.64 km/s and in sunlight.
What is Kosmos-546?
A navigation satellite in low Earth orbit, in space since Jan 26, 1973.
Can I see Kosmos-546?
No, not with the naked eye: no brightness has been published for Kosmos-546, and nothing here estimates one; receivers on the ground use its signals instead, whenever it is above their horizon.

No operator publishes an ephemeris for Kosmos-546, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Kosmos-546 has been reported publicly in the past thirty days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 8, 2026, 2:43 PM, 9 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.
