Uncertainty of planetary orbital period

AI Thread Summary
Data on the uncertainty of planetary orbital periods, particularly for Jupiter, is not readily available, with one source citing "1 arcsec per 250 years" but lacking verification. Researchers suggest looking into journal papers focused on precise planetary ephemerides, specifically JPL's DE series and IMCCE's INPOP. These resources may provide the needed data and can be found through platforms like Google Scholar or arXiv.org. The discussion highlights a common challenge in finding reliable information on this topic. Further exploration of academic literature is recommended for accurate figures.

I've been searching all over the place, and I cannot find any data showing the error bars of orbital periods of planets. Once source estimates the uncertainty of Jupiter to be "1 arcsec per 250 years" but I cannot find anything to back this up.

Does anybody have any hints as to where I should be looking?

Jack, this is a great question, I have been wondering exactly the same thing. I see no one here replied, but did you find this data somewhere else?
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
