In view from you

Nobody watches RUBIN 4/SL-8 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 RUBIN 4/SL-8, 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.

Timeline

  1. Launch

    Launched, on the day GCAT records. Source

  2. Close approach

    On Thursday, Oct 15 at 12:51 AM UTC, a fragment of Fengyun 1C (NORAD 37719) was to pass within 954 m of Rubin 4/SL-8 (NORAD 27940). The chance was about 1 in 7,000.

No operator publishes an ephemeris for RUBIN 4/SL-8, so every position here comes from its orbital elements.

In orbit

Close approaches
1 reported. No close approach to RUBIN 4/SL-8 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.
