(meteorobs) perihelion
Jean,
Thanks for that clarification. As usual I was thinking
incorrectly too early in the morning. If you think about how the send all
those deep-space probes around planets to get a speed boost it makes perfect
sense the greatest velocity is at the perihelion.

Kepler found in his second law for ellipses and then Newton found for any
conic section (elliptic, parabolic or hyperbolic) that the highest speed is
at the perihelion.
