In view from you
Nobody watches BEIDOU 3M23 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 BEIDOU 3M23, 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.
Summary
Over the Pacific Ocean LIVE
Where is BEIDOU 3M23?
At 4:41:41 PM UTC BEIDOU 3M23 was over the Pacific Ocean (6.7° N, 115.6° W), 21,501 km up, moving at 3.78 km/s and in sunlight.
What is BEIDOU 3M23?
A BeiDou navigation satellite in medium Earth orbit, in space since Sep 22, 2019.
Can I see BEIDOU 3M23?
No, not with the naked eye: no brightness has been published for BEIDOU 3M23, 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 BEIDOU 3M23, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to BEIDOU 3M23 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
BEIDOU 3M23 shares its launch, 2019-061, with 2 other bodies the catalogue lists in orbit.
