Misleading picture![edit]

This picture is wrong: the mean anomaly shows two units of time (the first 2 slices of the big circle, i.e. respectively the white and pink slices after the pericenter, counterclockwise), whereas the true anomaly shows three units of time (the first 3 slices of the small ellipse, i.e. respectively the grey, pink and grey slices after the pericenter, counterclockwise). Both anomalies should be moved on the same unit; moving the mean anomaly to unit 3 is probably easier, but it requires moving the label, as it is now in the way of the arrow. --5.23.32.98 13:47, 12 December 2016 (UTC)[reply]

The picture is right. The mean anomaly indeed shows two units of time (first a white slice, then a pink slice of the circle). And the true anomaly shows two units of time as well (first a white slice of the ellipse, then a grey slice). Note that the first slice of the ellipse is not only white, but also contains pink from the circle. Nevertheless the pink sub-slice in the ellipse is part of the first white/non-grey slice of the ellipse. Kerel-fs (talk) 13:05, 1 June 2023 (UTC)[reply]
