Ejemplos de uso de PERIAPSIS en una oración

• Eccentric anomaly, the angle between the direction of periapsis and the current position of an object on its orbit.
• On December 20, 1976, the periapsis was lowered to 778 km, and the inclination raised to 80 degrees.
• The portion of the semi-major axis extending from the primary at one focus to the periapsis is shown as a purple line in the diagram; the rest (from the primary/focus to the center of the orbit ellipse) is below the reference plane and not shown.
• Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit (apoapsis) by flying the vehicle through the atmosphere at the low point of the orbit (periapsis).
• Each spacecraft was in a nearly polar orbit with a periapsis ~1000 km, at 62°N latitude, and apoapsis ~65000 km, with an inclination ~90°, the orbital period being ~24 hours.
• Upon arriving in lunar orbit, Stafford and Cernan undocked in the LM and entered an elliptical orbit with a periapsis (the closest distance) of nine miles over the lunar surface.
• This is often true for orbits that begin as circular, as drag forces are considered "re-circularizing", since drag magnitudes at the periapsis (lower altitude) is expectedly greater than that of the apoapsis, which has the effect of reducing the mean eccentricity.
• If the inclination is large enough, the eccentricity can in turn grow so large that the periapsis of the satellite (called the perijove in the case of moons of Jupiter) would be in the immediate vicinity of the Galilean moons (Io, Europa, Ganymede and Callisto).
• In celestial mechanics, the eccentricity vector of a Kepler orbit is the dimensionless vector with direction pointing from apoapsis to periapsis and with magnitude equal to the orbit's scalar eccentricity.
• The argument of periapsis (also called argument of perifocus or argument of pericenter), symbolized as ω (omega), is one of the orbital elements of an orbiting body.
• In celestial mechanics, the longitude of the periapsis, also called longitude of the pericenter, of an orbiting body is the longitude (measured from the point of the vernal equinox) at which the periapsis (closest approach to the central body) would occur if the body's orbit inclination were zero.
• The first impulse to change the spacecraft's orbit is performed at a specific point in the original orbit (point of impulse, POI), usually performed in the original orbit's periapsis or apoapsis.
• For Earth, orbital eccentricity , apoapsis is aphelion and periapsis is perihelion, relative to the Sun.
• An elliptical orbit is most easily converted to a circular orbit at the periapsis or apoapsis by applying a single engine burn with a delta v equal to the difference between the desired orbit's circular velocity and the current orbit's periapsis or apoapsis velocity:.
• Since increasing eccentricity while keeping the semimajor axis constant reduces the distance between the objects at periapsis, this mechanism can cause comets (perturbed by Jupiter) to become sungrazing.
• Likewise, dropping periapsis all the way into the atmosphere of a planetary body for aerobraking is inexpensive in velocity at apoapsis, but permits the use of "free" drag to aid in the final circularization burn to drop apoapsis; though it adds an extra mission stage of periapsis-raising back out of the atmosphere, this may, under some parameters, cost significantly less delta V than simply dropping periapsis in one burn from circular orbit.
• The apsides are the two points of closest and furthest distance of the orbit (the periapsis and apoapsis, respectively); apsidal precession corresponds to the rotation of the line joining the apsides.
• If the craft is landing on a planet with an atmosphere such as Mars the deorbit burn will only lower periapsis into the upper layers of the atmosphere, rather than just above the surface as on an airless body.
• The apsides are the orbital points farthest (apoapsis) and closest (periapsis) from its primary body.
• Finally, a Perijove Raising Manoeuvre (PRM) burn at apoapsis will raise the periapsis of Juice's initial 13x243 Jovian radii elongated orbit to match that of Ganymede (15 Rj).
