In view from you

Nobody watches P71-2 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 P71-2, 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 to see with the naked eye from anywhere on Earth.

  2. Close approach

    On Tuesday, Nov 3 at 11:49 PM UTC, a fragment of Fengyun 1C (NORAD 30699) was to pass within 603 m of Astex 1 (NORAD 5560). The chance was about 1 in 3,000.

No operator publishes an ephemeris for P71-2, so every position here comes from its orbital elements.

In orbit

Close approaches
1 reported. No close approach to P71-2 is reported for the next three 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.
