  2. True anomaly - Wikipedia

    en.wikipedia.org/wiki/True_anomaly

    In celestial mechanics, true anomaly is an angular parameter that defines the position of a body moving along a Keplerian orbit.It is the angle between the direction of periapsis and the current position of the body, as seen from the main focus of the ellipse (the point around which the object orbits).

  3. Orbital elements - Wikipedia

    en.wikipedia.org/wiki/Orbital_elements

    True anomaly (ν, θ, or f) at epoch (t 0) defines the position of the orbiting body along the ellipse at a specific time (the "epoch"), expressed as an angle from the periapsis. The mean anomaly M is a mathematically convenient fictitious "angle" which does not correspond to a real geometric angle, but rather varies linearly with time, one ...

  4. Eccentric anomaly - Wikipedia

    en.wikipedia.org/wiki/Eccentric_anomaly

    The true anomaly is the angle labeled in the figure, located at the focus of the ellipse. It is sometimes represented by f or v. The true anomaly and the eccentric anomaly are related as follows. [2] Using the formula for r above, the sine and cosine of E are found in terms of f :

  5. True longitude - Wikipedia

    en.wikipedia.org/wiki/True_longitude

    The true longitude l can be calculated as follows: [1] [2] [3] l = ν + ϖ. where: ν is the orbit's true anomaly, ϖ ≡ ω + Ω is the longitude of orbit's periapsis, ω is the argument of periapsis, and; Ω is the longitude of the orbit's ascending node,

    A war of words between Elon Musk and Sam Altman escalated on social media Thursday, as two of the most powerful men in tech sparred over their rival artificial intelligence initiatives.

  8. Mean longitude - Wikipedia

    Its true longitude is calculated similarly, l = Ω + ω + ν, where ν is the true anomaly. Define a reference direction, ♈︎, along the ecliptic. Typically, this is the direction of the March equinox. At this point, ecliptic longitude is 0°.
