digraph {
   "poliastro.core.util" -> "circular_velocity", "rotate", "transform" ;
}

The poliastro.core.util module contains, mainly, a set of functions realted to vectorial computations.

poliastro.core.util.circular_velocity

Compute circular velocity for a given body given thegravitational parameter and the semimajor axis.

\[v = \sqrt{\frac{\mu}{a}}\]
Parameters:
  • k (float) – Gravitational Parameter
  • a (float) – Semimajor Axis
