In view from you
Nobody watches Telstar 402R 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 Telstar 402R, 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 for the naked eye. What reaches you from it reaches a dish or an antenna, not an eye.

- Close approach
On Friday, Oct 9 at 6:25 PM UTC, the rocket body of Titan 3C Transtage (NORAD 9855) was to pass within 4.5 km of Telstar 4 (Telstar 402R) (NORAD 23670).
Summary
Over the Pacific Ocean LIVE
Where is Telstar 402R?
At 6:45:47 PM UTC Telstar 402R was over the Pacific Ocean (9.6° S, 94.1° W), 35,782 km up, moving at 3.08 km/s and in sunlight.
What is Telstar 402R?
A communications satellite in an inclined geosynchronous orbit, in space since Sep 24, 1995.
Can I see Telstar 402R?
No, not with the naked eye: no brightness has been published for Telstar 402R, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Telstar 402R, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to Telstar 402R 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.
Launched with
Telstar 402R shares its launch, 1995-049, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| ARIANE 42L+3 R/B | Rocket body |
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.
