While nominally a simple longitude, in practice the mean longitude does not correspond to any one physical angle. From these definitions, the "mean longitude", "l", is the angular distance the body would have from the reference direction if it moved with uniform speed, measured along the ecliptic from ♈︎ to the ascending node, then up along the plane of the body's orbit to its mean position. Mean longitude, like mean anomaly, does not measure an
