Close Approach of (415029) 2011 UL21
#6
Hi BMD,

Thanks for the info about the differences in the orbital elements of 2024 MK and (415029) 2011 UL21. I don't know that I'd consider a 0.1 km object tiny. It would certainly leave a mark. NEOs with H=22 magnitude are generally considered to be ~140 m diameter and 2024 MK is slightly larger than that with H=21.76 magnitude. CNEOS has q=1.009168587376742 AU and lists it as an Apollo object and a PHA.

I saw your entry in the Support section regarding the use of kilometers where SkyTools expects AUs. As a temporary fix, can you manually convert the km units to AUs? Only a and q would need to be converted. I haven't used HORIZONS to obtain elements in a while. Can you request that the a and q parameters are generated as AU instead of km?

(415029) 2011 UL21 is already 13.9 magnitude according to ST4 Visual, but in Pyxis.

Phil S.
