The LRL vector is usually scaled by the namesake vector of this quantity. This quantity equals thesquare root of 1 plus two times the energy times angular momentum squared over the mass times Big Gsquared. This quantity multiplies the sine of its namesake anomaly, then is subtracted from that anomaly,in order to calculate the mean anomaly. For Earth, this quantity is approximately 0.016. This quantitymultiplies the cosine of the angle to the point of (*) closest approach in the denominator of a mathematicaldescription of Kepler's First Law. The nonzero value for this quantity explains why the time between equinoxes isnot equal. For 10 points,
