In celestial mechanics, the mean anomaly is the fraction of an elliptical orbit's period that has elapsed since the orbiting body passed periapsis, expressed as an angle which can be used in calculating the position of that body in the classical two-body problem. It is the angular distance from the pericenter which a fictitious body ...The longitude of the ascending node (☊ or Ω) is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending node, as measured in a specified reference plane.

Having no combat skills has the advantage of being able to choose your own without having points wasted into junk.Multiple systems are used in the study of space, and by extension astrodynamics. Every coordinate system consists of three mutually perpendicular axes that describe the three-dimensional coordinates of all points in space. Each particular system is defined by three geometric objects: an origin, a reference direction and a fundamental plane. Converting between CGS and SI units is easy because the conversion factors are all powers of 10, as reviewed in the table below. For example, 100 cm = 1 m and 1,000 g = 1 kg. The CGS unit of force is called the dyne, which is 1 g cm/s, so a Newton (N) in SI units equals 100,000 dynes in CGS units.
