How long is a mean Jovian tropical year in Jovian solar days?
Many sources say that Jupiter's year lasts 10,475.8 Jovian days. When I calculated to see if that's correct With the data NASA had published, I found out it's the measurement of a Jovian sidereal year. How many Jovian solar days are there in one mean Jovian tropical year EXACTLY?

1. But as it turns out, a Jovian day is officially only 9 hours, 55 minutes and 30 seconds long, which means a single day is just over a third the length of an Earth day.
2.Whenever the longitude reaches a multiple of 360 degrees the mean Sun crosses the vernal equinox and a new tropical year begins". The mean tropical year in 2000 was 365.24219 ephemeris days; each ephemeris day lasting 86,400 SI seconds. This is 365.24217 mean solar days.
