In view from you

Nobody watches Telstar 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.

Even at its closest, Telstar 1 is too faint to see with the naked eye from anywhere on Earth, so no city page carries pass times for it.

Seeing it

There is nothing to go outside for: it is too faint for the naked eye. It is still up there all the same, going round as it has since it was launched.

Summary

Over the Pacific Ocean LIVE

Where is Telstar 1?

At 4:11:00 AM UTC Telstar 1 was over the Pacific Ocean (44.2° S, 121.6° W), 4,807 km up, moving at 5.49 km/s and in sunlight.

What is Telstar 1?

One of the pioneers of spaceflight in medium Earth orbit, in space since Jul 10, 1962; its mission ended on Feb 21, 1963.

Can I see Telstar 1?

No, not with the naked eye: even at its closest, Telstar 1 is too faint to see from anywhere on Earth; what it is now is a relic of the first years in orbit.

Close approaches
No close approach to Telstar 1 has been reported publicly in the past thirty days.

From Space-Track’s public conjunction messages; the latest report was issued Nov 2, 2026, 1:53 PM, 13 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.
