I am trying to use ``get_body`` to get the RA/Dec for the sun on a certain date, and am interested in getting the apparent coordinates consistent with JPL horizons. If I go to [Horizons](https://ssd.j…

I'm a recent user of Skyfield and it's been an excellent tool! I've been looking at satellite illuminations and was using JPL's Horizon app as a check. I was working through your ISS example from "Bl…

Hi,
I am trying to generate ephemeris for astronomical observations from Hubble Space Telescope (LEO) and the Euclid Space Telescope (Lagrangian point 2). As far as I understand from the documenta…

I'm trying to get the RA/Dec of an asteroid from the position of a satellite. I have the satellite's lat/lon/altitude, and I get the asteroid position from astroquery's jpl horizons package. The res…
