WebSemimajor axis ( a) — The sum of the periapsis and apoapsis distances divided by 2. Periapsis is the point at which an orbiting object is closest to the center of mass of the body it is orbiting. Apoapsis is the point at which an orbiting object is farthest away from the center of mass of the body it is orbiting. WebA gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. cuchulainn meaningWebAug 4, 1981 · The point closest to the attracting body is called periapsis, while the … easter bunny headband ears

An apsis is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, for orbits about the Sun the apsides are called aphelion (farthest) and perihelion (nearest). See more There are two apsides in any elliptic orbit.
