Cassini's Laws (1693) are three laws that deal with the motion of the Moon. Crust composition Oxygen 43% Silicon 21% Aluminium 10% Calcium 9% Iron 9% Magnesium 5% Titanium 2% Nickel 0. ...
The first law states that the Moon has 1:1 orbital resonance. This means that the rotation / orbit of the Moon is such that the same face is always facing the Earth. Orbital Resonance is also the title of a science fiction novel by John Barnes. ... Rotation is the movement of a body in such a way that the distance between a certain fixed point and any given point of that body remains constant. ... In physics, an orbit is the path that an object makes, around another object, whilst under the influence of a source of centripetal force, such as gravity. ... Earth, also known as the Earth, Terra, and (mostly in the 19th century) Tellus, is the third planet outward from the Sun. ...
The second law claims that the Moon's rotational axis maintains the same angle of inclination from the ecliptic plane. In which case the Moon's axis forms a cone and the moons orbit is a cicle where this cone intersects the ecliptic plane. Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees. ... The plane of the Ecliptic is well seen in this picture from the 1994 lunar prospecting Clementine spacecraft. ...
