In view from you
Nobody watches Navstar 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 Navstar 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 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 Navstar 2?
At 5:35:58 PM UTC Navstar 2 was over the Pacific Ocean (4.4° N, 133.3° E), 21,054 km up, moving at 3.74 km/s and in sunlight.
What is Navstar 2?
A navigation satellite in medium Earth orbit, in space since May 13, 1978.
Can I see Navstar 2?
No, not with the naked eye: no brightness has been published for Navstar 2, 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 Navstar 2, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Navstar 2 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
Navstar 2 shares its launch, 1978-047, with 2 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| ATLAS F R/B | Rocket body |
| ATLAS F 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.
