Current orbit
View on live mapOne orbit takes a day, as long as the Earth takes to turn, so Shi Jian 29B keeps above 73.3° E of the equator and never crosses the sky.
It never rises or sets
Shi Jian 29B 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 Shi Jian 29B, 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.

In orbit
- Close approaches
- No close approach to Shi Jian 29B 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
Shi Jian 29B shares its launch, 2025-315, 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.
