The overhanging cliff in the painting can still be seen from the monastery today and is at an azimuth of 128* (south-east) and an altitude of 6 (just above the horizon). Notice the bright yellow object in the sky centered on the cliff? What was it? The Sun or the Moon? In Stellarium Web paste 43.78858, 4.83175 into the location search box. Orient Stellarium so that you have a clear view of the horizon in the south-east on July 13, 1889.

According to Stellarium, what planet could have inspired Van Gogh to paint a fainter star in that location? e. How does the position of these three celestial bodies differ between the painting and their actual positions in the night sky?
