Add a definition As a planet approachesperiapsis, the planet will increase in speed, or velocity. From Wikipedia ![]() Particularly at eachperiapsis, the object experiences atmospheric drag, losing energy. From Wikipedia ![]() For near-circular orbits, it is hard to find theperiapsisin the first place (and truly circular orbits have noperiapsisat all). From Wikipedia ![]() The last time they were atperiapsiswas in 1836. From Wikipedia ![]() The ecliptic longitudes of theperiapsisof the satellite and the planet are locked. From Wikipedia ![]() The initial, high eccentricity orbits may also be a source of gravitational waves, emitting a short burst as the compact object passes throughperiapsis. From Wikipedia ![]() It had aperiapsisof 171 km and an apoapsis of 3,524 km and an orbital period of 619 minutes. From Wikipedia ![]() These variations are connected with the variations of the ring width, which is 19.7 km at theperiapsisand 96.4 km at the apoapsis. From Wikipedia ![]() When gradually making an elliptic orbit smaller, it means applying thrust each time when near theperiapsis. From Wikipedia ![]() With increasing release height the orbit becomes less eccentric as bothperiapsisand apoapsis increase, becoming circular at geostationary level. From Wikipedia ![]() The angular rate is faster nearerperiapsisand slower near apoapsis. From Wikipedia ![]() Thereafter, theperiapsiswas allowed to rise to a maximum of and then fall, to conserve fuel. From Wikipedia ![]() The point on the orbit closest to the attracting body is theperiapsis. From Wikipedia ![]() When gradually making an elliptic orbit larger, it means applying thrust each time when near theperiapsis. From Wikipedia ![]() So to get the most kinetic energy from the burn, the burn must occur at the vehicle's maximum velocity, atperiapsis. From Wikipedia ![]() Adding the argument ofperiapsisto the longitude of the ascending node gives the longitude of theperiapsis. From Wikipedia ![]() A line drawn fromperiapsisto apoapsis is the line-of-apsides. From Wikipedia ![]() For the most efficient example mentioned above, targeting an inclination at apoapsis also changes the argument ofperiapsis. From Wikipedia ![]() A straight line connecting theperiapsisand apoapsis is the "line of apsides". From Wikipedia ![]() These examples are from corpora and from sources on the web.
