physics.basic_orbital_capture.capture_area(capture_radius: float) → float

Input Param:

capture_radius: The radius of orbital capture and impact for a central body of mass M and a projectile moving towards it with velocity v

SI units: meters | m

Returns:

>>> capture_area(17209590691)
9.304455331329126e+20
>>> capture_area(-1)
Traceback (most recent call last):
    ...
ValueError: Cannot have a capture radius less than 0

Returned SI units:

meters*meters | m**2

physics.basic_orbital_capture.capture_radii(target_body_radius: float, target_body_mass: float, projectile_velocity: float) → float

Input Params:

target_body_radius: Radius of the central body SI units: meters | m target_body_mass: Mass of the central body SI units: kilograms | kg projectile_velocity: Velocity of object moving toward central body

SI units: meters/second | m/s

Returns:

>>> capture_radii(6.957e8, 1.99e30, 25000.0)
17209590691.0
>>> capture_radii(-6.957e8, 1.99e30, 25000.0)
Traceback (most recent call last):
    ...
ValueError: Radius cannot be less than 0
>>> capture_radii(6.957e8, -1.99e30, 25000.0)
Traceback (most recent call last):
    ...
ValueError: Mass cannot be less than 0
>>> capture_radii(6.957e8, 1.99e30, c+1)
Traceback (most recent call last):
    ...
ValueError: Cannot go beyond speed of light

Returned SI units:

meters | m
