My Jupiter/Saturn conjunction calculation with skyfield doesn't match wikipedia

QUESTION

My Jupiter/Saturn conjunction calculation with skyfield doesn't match wikipedia

Asked 2020-Nov-18 at 21:03

Using Python-Skyfield to calculate the upcoming conjunction if Jupiter and Saturn.

Wikipedia Great conjunction times (1800 to 2100)

Using Right Ascension:

Dec 21,2020 13:22:00 UTC - Wikipedia.
Dec 21,2020 13:34:33 UTC - My Calculation.

Using Ecliptic Longitude:

Dec 21,2020 18:37:31 UTC - Wikipedia
Dec 21,2020 18:20:40 UTC - My Calculation.

I have tried my best to avoid my feel of possibility of opinion based answers on this question and looked this up on internet. Found out it is quite hard to find any relevant info that I could trust, so I enumerate these posts (except wikipedia):

timeanddate is stating the exact time is 18:20 UTC on December 21, which is as you have calculated

winstars have stated the time when the planets will be at closest angle as 18:25 UTC and they mention that conjunction will occur at 13:30 UTC, I am not sure if that is the first time.

Not sure how relevant is this, but the conjunction here is stated to be 6.2 degreest at 17:32 GMT, thus 18:32 UTC

The most relevant source I was able to find was in the sky, where the time was estimated exactly to 13:24 UTC., based on calculations on data by Jet Propulsion Laboratory - source code can be checked here (c).

You can see that mostly not both types of calculation are used, and that the times vary. The reason of that is that in such calculations you need very long floats for best precision. As you are limited by the machine you use, the precision is not perfect. Such as @bad_coder has suggested, you might get better answer in Astronomy stack exchange.
