Rising, transit and setting is my next function... This is a difficult one. When I do it last year on Mathematica I use the interpolation. The problem is that the time for the three moments are not always in the same cycle for the object. The Sun is not a problem because it always rise in the morning. But a planet can rise at 23 hours and set a 7 hours the next day. In that case the program will not calculate these two moment because the occur at two differents days. Here the user must understand this concept.

I know it's a bit tricky.
For the Moon is very hard to do, if one wants precise results.
We must calculate a "standard" height for the body and for the Moon this is connected to parallax also...
I'm doing a separate function but perhaps I must also separate RA/declination from Sun, Moon, Planet to can use interpolation...

For now my program returns "almost right" results, I think...
