Current orbit
View on live mapOne orbit takes a day, as long as the Earth takes to turn, so Kosmos-2520 keeps above 45° E of the equator and never crosses the sky.
It never rises or sets
Kosmos-2520 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 Kosmos-2520, 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 Indian Ocean LIVE
Where is Kosmos-2520?
At 5:35:19 PM UTC Kosmos-2520 was over the Indian Ocean (0° N, 45° E), 35,786 km up, standing over one longitude of the equator and in sunlight.
What is Kosmos-2520?
A communications satellite in geostationary orbit, in space since Aug 16, 2017.
Can I see Kosmos-2520?
No, not with the naked eye, and it never crosses the sky: Kosmos-2520 stands over 45° E of the equator; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Kosmos-2520, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Kosmos-2520 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.
Launched with
Kosmos-2520 shares its launch, 2017-046, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| BREEZE-M R/B | Rocket body |
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.
