This was an extra credit project for my Exploration of Space course Spring 2009. One of my more creative endeavors:-D

Keplers Laws All Three

A natral orbits controlled by gravity
Celestial Bodies all follow, follow one.
Spaceships with their engines off, orbit in one too
Keplers Laws explain them and theres only 3 to know
Orbits arent circles
The planets move in ellipses you see

Suddenly I see (Suddenly I see)
Pariapsis is close to gravity
Suddenly I see (Suddenly I see)
Apopapsis is farthest from gravity

Suddenly I see (Suddenly I see)
For earth close is perigee
Suddenly I see (Suddenly I see)
The farthest from the Earth is apogee

The first law talks about the orbits shape
If its bound its elliptical, elliptical.
Theres 2 foci with the occupied
The major axis is the largest diameter of it
Unbound orbits
Are called hyperbolic in shape

Suddenly I see (Suddenly I see)
Round means low eccentricity
Suddenly I see (Suddenly I see)
Our planets make orbits like these

Suddenly I see (Suddenly I see)
Stretched is high eccentricity
Suddenly I see (Suddenly I see)
Astroids and comets are like these
[

And the second law is
At the pariapsis and slowest at apoapsis
The third law talks about the period
The time to make an orbit
The bigger the major axis the longer the period

The bigger the major axis the greater total energy
Periapsis has the greatest energy of motion

Apoapsis has the greatest energy of position

Total Energys the same at any point in orbit

Suddenly I see (Suddenly I see)
Total Energys the sum
Suddenly I see (Suddenly I see)
Of energy of motion and position

Suddenly I see (Suddenly I see)
The sum is constant
Suddenly I see (Suddenly I see)
Because of conservation of energy

Suddenly I see (Suddenly I see)
Bound orbits have negative total energy
Suddenly I see (Suddenly I see)
Unbound have positive total energy

Suddenly I see (Suddenly I see)
These are Keplers Laws all three
Suddenly I see (Suddenly I see)
They explain the solar system cant you see.
