Bug#591213: planets: physics engine appears to have errors at small distances

[Russell Coker <russell@coker.com.au>]

Package: planets
Version: 0.1.13-11
Severity: normal

When a large planet has a small planet bouncing off it then periodically one of
the bounces will be unusually large and bounce it well away from the large
planet.

I guess that this is a problem where the accelleration is calculated based on
the gravitational force at a small distance and that force is considered to
apply for one time period even though the object would have bounced off before
the time period ended.
