The argument of periapsis (ω) is the orbital element describing the angle of an orbiting body’s periapsis (the point of closest approach to the central body), relative to its ascending node (the point where the body crosses the plane of reference from South to North). … may replace the word “periapsis”.

## How do you change the argument of periapsis in KSP?

If anyone is wondering how to change the argument of periapsis & longitude of ascending node. This is how. You can do it with by using the following maneuvers: **Tilting the plane by burning to normal/anti-normal (LoA) and rotating the plane (AoP) by burning to radial in/out**.

## Does argument of perigee change?

If we were to model the Earth as a perfect sphere with a uniform gravitational field, the RAAN and **argument of perigee would not change**. But since our Earth is not really a perfect sphere, it is important that we account for this perturbation.

## How do you raise periapsis in KSP?

Change orbital shape

Raise your apoapsis **by burning prograde at your periapsis instead**. Lower your periapsis by burning retrograde at your apoapsis.

## How do you match orbits in KSP?

By simply adjusting your orbital period, you will eventually time it so both craft are at the overlapping point at the same time. At that close approach (~<3km), make sure the NAVball is in Target Mode. **Burn retrograde down to 0m/s relative** velocity. This will have the effect of matching orbits.

## What are the six Keplerian elements?

**In implementation, then, the 6 elements are:**

- a = Semi-major axis = size.
- e = Eccentricity = shape.
- i = inclination = tilt.
- ω = argument of perigee = twist.
- Ω = longitude of the ascending node = pin.
- v = mean anomaly = angle now.

## How do you find an argument of latitude?

It is the angle between the ascending node and the body. It is the sum of the more commonly used true anomaly and argument of periapsis. **u=ν+ω** where u is the argument of latitude, ν the true anomaly, and ω the argument of periapsis.

## What’s the meaning of perigee?

: **the point in the orbit of an object (such as a satellite) orbiting the earth that is nearest to the center of the earth** also : the point nearest a planet or a satellite (such as the moon) reached by an object orbiting it — compare apogee.

## What’s the difference between Apoapsis and Apogee?

is that apogee is (astronomy) the point, in an orbit about the earth, that is furthest from the earth: the **apoapsis of an** earth orbiter while apoapsis is (astronomy) the point of a body’s elliptical orbit about the system’s centre of mass where the distance between the body and the centre of mass is at its maximum.
