Is the precession of the orbit of Mercury accounted for?

[issantos]

The perihelion of Mercury shifts over time due to relativistic effects. Is this accounted for in Stellarium?

You can be very sure about this. Stellarium replays simulation results from VSOP87, DE430, DE431, DE440 or DE441.

I placed DE43x and DE44x into C:\Users\Andi Pangerang\AppData\Roaming\Stellarium\ephem folder
also into C:\Program Files\Stellarium\ephem and C:\Program Files (x86)\Stellarium\ephem folders respectively

why it doesn't appear?

[alex-w]

Stellarium expect to see files like linux_p1550p2650.440 in ephem directory as it described in User Guide - not BSP!
