astrodynx.right_ascension#
- astrodynx.right_ascension(node_vec)[source]#
Returns the right ascension of the ascending node of a two-body orbit.
- Parameters:
node_vec (
ArrayLike) – (…, 3) node vector of the object in the two-body system.- Return type:
- Returns:
The right ascension of the ascending node of the orbit.
- Notes
The right ascension is calculated using equation:
\[ \Omega = \arctan2(N_y, N_x) \]where \(\Omega\) is the right ascension of the ascending node, \(N_y\) is the y-component of the node vector, and \(N_x\) is the x-component of the node vector.
