In view from you
Nobody watches Feng Yun 3F 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 Feng Yun 3F, 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 it is up there for reaches the ground as pictures and measurements, not as a light in the sky.

What is Feng Yun 3F?
A satellite that watches the Earth in low Earth orbit, in space since Aug 3, 2023.
Can I see Feng Yun 3F?
No, not with the naked eye: no brightness has been published for Feng Yun 3F, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for Feng Yun 3F, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Feng Yun 3F 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
Feng Yun 3F shares its launch, 2023-111, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| CZ-4C 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.
