The apsides refer to the farthest (2) and nearest (3) points reached by an orbiting planetary body (2 and 3) with respect to a primary, or host, body (1).

(When orbiting the Earth, the last two terms are known as the apogee and perigee.) It is common to specify the period instead of the semi-major axis a in Keplerian element sets, as each can be computed from the other provided the standard gravitational parameter, GM, is given for the central body.
A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth.Examples of inclined HEO orbits include Molniya orbits, named after the Molniya Soviet communication satellites which used them, and Tundra orbits.
r a is the radius at apoapsis (also "apofocus", "aphelion", "apogee"), i.e., the farthest distance of the orbit to the center of mass of the system, which is a focus of the ellipse. r p is the radius at periapsis (or "perifocus" etc.), the closest distance.
Scott Miller (born 1961) is an American video game designer, programmer, and entrepreneur best known for founding Apogee Software (which later became 3D Realms) in 1987. . Starting with the Kroz series for MS-DOS from that year, Miller pioneered the concept of giving away the first game in a trilogy—distributed freely as shareware—with the opportunity to purchase the remaining two episode
