In view from you
Nobody watches P83-1 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 P83-1, 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.

No operator publishes an ephemeris for P83-1, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to P83-1 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
P83-1 shares its launch, 1983-063, with 3 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| SCOUT G-1 R/B | Rocket body |
| SCOUT G-1 DEB | Debris |
| SCOUT G-1 DEB | Debris |
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.
