Examples of periapsis
periapsis
A straight line drawn through the periapsis and apoapsis is the line of apsides.
From the en.wikipedia.org
As a planet approaches periapsis, the planet will increase in speed, or velocity.
From the en.wikipedia.org
Scientific instruments were generally turned on for about 30 minutes near periapsis.
From the en.wikipedia.org
Particularly at each periapsis, the object experiences atmospheric drag, losing energy.
From the en.wikipedia.org
The superior conjunction between Europa and Ganymede occurs when Europa is at periapsis.
From the en.wikipedia.org
A line drawn from periapsis to apoapsis is the line-of-apsides.
From the en.wikipedia.org
On 20 December 1976 the periapsis was lowered to 778 km and the inclination raised to 80 degrees.
From the en.wikipedia.org
The eccentricity of 0.7512 gives it an apoapsis that is seven times its periapsis distance from Neptune.
From the en.wikipedia.org
Subsequent motion of the panel at periapsis 16 through 18 caused the flight team to raise the orbit further on Oct.

- (astronomy) the point in an orbit closest to the body being orbited
- An apsis (Greek: u1F01u03C8u03AFu03C2; plural apsides /u02C8u00E6psu1D7Bdiu02D0z/, Greek: u1F01u03C8u03AFu03B4u03B5u03C2) is an extreme point in an object's orbit. The word comes via Latin from Greek and is cognate with apse...
- Point of closest approach for an object moving in an elliptical orbit about another celestial body. At this point in the orbit, the object is traveling at its greatest speed (Kepler's Second Law). ...
- The nearest point to the gravitational center in the orbit of any satellite. The suffix "apsis" may be modified to indicate a specific central body, thus perigee (Gaea=Earth), perihelion (Helios=Sun), periastron (astra=a star), etc. (G)
- The point in an orbit when two objects are closest together. Special names are given to this point for commonly used systems: see periastron, perihelion, and perigee. The opposite of apoapsis.
- The closest point in an orbit to the primary body. For earth orbits periapsis is known as perigee (see below).
