Planet Velocity Definition (More Analysis)
DATA No. (1)
5.9 x 0.8 = 4.7 km/s (Pluto velocity) BUT (5.9)^2 = 35 km/s (Venus velocity)
And
6.8 x 0.8 = 5.4 km/s (Neptune velocity) BUT (6.8)^2 = 47.4 km/s (Mercury velocity)
And
8.5 x 0.8 = 6.8 km/s (Uranus velocity) BUT (8.5)^2 = 2 x 35 km/s
And
12.12 x 0.8 = 9.7 km/s (Saturn

The vis viva equation, solved for the speed in orbit,
v = √[GM(2/r − 1/a)]
where
G = 6.6743e-11 m³ kg⁻¹ sec⁻²
M = 1.9885e+30 kg
a = semimajor axis of planet's orbit, meters
r = current distance between planet and sun, meters
P.S. I can explain how to get the position and velocity vectors of a planet in heliocentric ecliptic coordinates at a specified time from its Keplerian orbital elements, but this editor won't let me use the "less than" symbol in its mathematical sense; it always interprets it as an html tag initiator.
