In view from you

Nobody watches THEMIS D 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 THEMIS D, 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.

What is THEMIS D?

A satellite in a highly elliptical orbit, in space since Feb 17, 2007.

Can I see THEMIS D?

No, not with the naked eye: no brightness has been published for THEMIS D, and nothing here estimates one.

No operator publishes an ephemeris for THEMIS D, so every position here comes from its orbital elements.

In orbit

Close approaches
No close approach to THEMIS D 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.

See every close approach reported in orbit.
