What name is given to your angular distance on the Earth's surface relative to the equator?
Equator Equator An equator of a rotating spheroid (such as a planet) is its zeroth circle of latitude (parallel). It is the imaginary line on the spheroid's surface, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid's surface with the plane perpendicular to its axis of rotation and midway between its geographical poles. On Earth, "the Equator" is about long, of which 78.8% lies across water and 21.3% over land. Indonesia is the country straddling the greatest length of the equatorial line across both land and sea.

Relative angular momentum relative angular momentum (formula_10): where: Relative angular momentum In celestial mechanics, the relative angular momentum (formula_1) of an orbiting body (formula_2) relative to a central body (formula_3) is the moment of (formula_2)'s relative linear momentum: where: For a body in an unperturbed orbit about a central body, the orbital plane is stationary, and the relative angular momentum (formula_1) is perpendicular to the orbital plane. <br> For perturbed orbits where the orbital plane is in motion, the relative angular momentum vector is perpendicular to the (osculating) orbital plane at only two points in the orbit. In astrodynamics relative angular momentum is
