In view from you
Nobody watches Tiros 4 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 Tiros 4, 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 it is up there for reaches the ground as pictures and measurements, not as a light in the sky.

Summary
Over the Indian Ocean LIVE
Where is Tiros 4?
At 5:38:45 PM UTC Tiros 4 was over the Indian Ocean (41.9° S, 71.2° E), 801 km up, moving at 7.43 km/s and in the Earth’s shadow.
What is Tiros 4?
A satellite that watches the Earth in low Earth orbit, in space since Feb 8, 1962.
Can I see Tiros 4?
No, not with the naked eye: no brightness has been published for Tiros 4, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for Tiros 4, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Tiros 4 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
Tiros 4 shares its launch, 1962-002, with 3 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| DELTA 1 DEB (YO) | Debris |
| DELTA 1 DEB (YO) | Debris |
| DELTA 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.
