In view from you
Nobody watches Kosmos-90 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-90, 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 too faint for the naked eye. What reaches you from it reaches a dish or an antenna, not an eye.
Timeline
- Launch
Launched, on the day GCAT records. Source
- Close approach
On Wednesday, Oct 28 at 8:52 AM UTC, a fragment of CZ-4C (NORAD 38660) was to pass within 423 m of Cosmos 90 (NORAD 1588). The chance was about 1 in 4,000.
Summary
Over the Pacific Ocean LIVE
Where is Kosmos-90?
At 5:25:02 AM UTC Kosmos-90 was over the Pacific Ocean (40.5° N, 156.9° E), 1,629 km up, moving at 7.02 km/s and in sunlight.
What is Kosmos-90?
A communications satellite in low Earth orbit, in space since Sep 18, 1965.
Can I see Kosmos-90?
No, not with the naked eye: no brightness has been published for Kosmos-90, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Kosmos-90, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to Kosmos-90 is reported for the next three 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.
