Io's tidal bulge of as much as 100 metres(330 ft) as Jupiter's gravitational pull varies between the periapsis and apoapsis points in Io's orbit.
The angle between the direction of periapsis and an asymptote from the central body is the true anomaly as distance tends to infinity( θ∞{\displaystyle\theta_{\infty}\,}),
The eccentricity of an elliptical orbit can also be used to obtain the ratio of the periapsis to the apoapsis: r p r a 1- e 1+ e{\displaystyle{{ r_{\ text{ p}}}\over{r_{\text{a 1-e}\over{1+e}}} For Earth, orbital eccentricity≈ 0.0167, apoapsis= aphelion and periapsis= perihelion relative to sun.
The converse is also true- a body does not need to be slowed by much compared to its hyperbolic excess speed(e.g. by atmospheric drag near periapsis) for velocity to fall below escape velocity and so for the body to be captured.
For elliptical orbits it can also be calculated from the periapsis and apoapsis since rp a( 1- e) and ra a( 1+ e), where a is the semimajor axis. e r a- r p r a+ r p 1- 2 r a r p+ 1{\ displaystyle{\ begin{ aligned} e&={{ r_{\ text{ a}}- r_{\ text{ p}}}\ over{ r_{\ text{ a}}+ r_{\ text{ p}}}} \\&=1-{\ frac{ 2}{{\ frac{ r_{\ text{ a}}}{ r_{\ text{ p}}}} +1}}\ end{ aligned}}} where: ra is the radius at apoapsis( i.e., the farthest distance of the orbit to the center of mass of the system, which is a focus of the ellipse). rp is the radius at periapsis the closest distance.
The main axis of the ellipse that connects periapsis and apoapsis of an orbit is called the line of apsis.
After passing the periapsis, kinetic energy is converted back into potential energy.
Rp is the radius at periapsis(the closest distance).
This still applies to your periapsis during a gravity assist.
Argument of periapsis From Wikipedia, the free encyclopedia.
The point on the orbit closest to the attracting body is the periapsis.
As a planet approaches periapsis, the planet will increase in speed, or velocity.
If fuel is scarce, any periapsis below 70 km will eventually result in de-orbiting.
The main axis of the ellipse that connects the periapsis and apoapsis an orbit is called line of apsis.
2.5, being highest near the periapsis.
For the eccentricity and argument of periapsis parameters, eccentricity zero(circular orbit)
As a vehicle falls towards periapsis in any orbit(closed or escape orbits) the velocity relative to the central body increases.
With e> 2{\displaystyle e>2} the asymptotes are more that 120° apart, and the periapsis distance is greater than the semi major axis.
The Periapsis is the closest point between a celestial object
A line drawn from periapsis to apoapsis is the line-of-apsides.
