In view from you
Nobody watches Kosmos-1428 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-1428, 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.
Timeline
- Launch
Launched, on the day GCAT records. Source
- Close approach
On Sunday, Oct 11 at 7:46 PM UTC, a fragment of Cosmos 1275 (NORAD 39958) was to pass within 915 m of Cosmos 1428 (NORAD 13757). The chance was about 1 in 7,000.
Summary
Over the Ross Sea LIVE
Where is Kosmos-1428?
At 6:43:41 PM UTC Kosmos-1428 was over the Ross Sea (73.8° S, 170.1° E), 988 km up, moving at 7.36 km/s and in sunlight.
What is Kosmos-1428?
A navigation satellite in low Earth orbit, in space since Jan 12, 1983.
Can I see Kosmos-1428?
No, not with the naked eye: no brightness has been published for Kosmos-1428, 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-1428, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to Kosmos-1428 is reported for the next three 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.
Launched with
Kosmos-1428 shares its launch, 1983-001, with 2 other bodies the catalogue lists in orbit.
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
