We already capture the location of an `Obj` at discovery time (`ra_dis` and `dec_dis`). But as more and more photometry is added (some with position) or deleted we should refine the `Obj` position (`r…

It appears that it is impossible to show an ephemeris of Pluto. I believe it is related to the "orbit_good" problem, but this is strange since Pluto is included in the DE440/DE441 ephemerides, meaning…

Hi,
I encountered this issue with JPLHorizons, but it might be present for other services.
For a brief moment, the Horizons API was returning errors to my queries.
Those queries have been st…

Hi,
I implemented VSOP87 and ELP2000-82B to calculate sun and moon geocentric positions, and wanted to validate my implementations against JPL ephemerides. Out of convenience, I used skyfield. Ever…

I made the observation that the GPS+GLONASS solution for singe as well as RTK kinematic is regularly worse than GPS only. No SBAS or other correction is used.
I don't know whether this is a M8T or R…

I tried visualizing the ephemeris of 2I/Borisov, but quickly found that it is limited to 2017-03-16. I get that the orbit is not accurate past that date, but it would still be interesting to view it t…

The aim was to detect if two satellites (with two different orbits) collide with each other or not. One proposal was to use the "Close Approach Analysis" by calculating the miss distance, as described…
