The eccentricity of the Moon's orbit can be calculated using the following formula. E = Vz / Vl = 0.0411 / 0.55 = 0.0747

Where Vz - Earth's orbital speed - 0.0411 degrees / hour.

Vl - Moon's orbital speed - 0.55 degrees / hour.

The eccentricity of the Moon's orbit can be calculated using the following formula.

E = (Vz / Sz) / (Vl / Sl) = 0.00071 / 0.0095 = 0.0747

Where Vz is the Earth's orbital speed - 107,218 km / h.

Sz - Distance from the Sun to the Earth - 150,000,000 km.

Where Vl is the Moon's orbital speed - 3683 km / h.

Sl - Distance from the Earth to the Moon 384,000 km.

The eccentricity of the Moon's orbit varies, from 0.026 to 0.077.

------------

Both formulas show that the average eccentricity of the Moon's orbit is 0.0747.

And the average eccentricity of the Moon's orbit, which is determined using radar, is 0.054.
