In view from you

Nobody watches Beidou DW 18 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 DW 18, 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 DW 18?

At 4:54:42 PM UTC Beidou DW 18 was over the Pacific Ocean (11.4° S, 176.4° W), 21,535 km up, moving at 3.78 km/s and in sunlight.

What is Beidou DW 18?

A navigation satellite in medium Earth orbit, in space since Jul 25, 2015.

Can I see Beidou DW 18?

No, not with the naked eye: no brightness has been published for Beidou DW 18, and nothing here estimates one; receivers on the ground use its signals instead, whenever it is above their horizon.

In orbit

Close approaches
No close approach to Beidou DW 18 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.
