Newton's Law seems to work!

SOLAR SYSTEM DATA – MOONS and RINGS                          Planets            Exoplanets
So Many, So Far Away

Moons  are natural objects that orbit planets, dwarf planets, and asteroids (minor planets). They vary in size from more than 5000 Km diameter to a few Km. Composed of rock and/or ice, they are held by gravitational forces to their primary planet.

<== Near Side Luna

Far Side Luna ==>

Most orbits are slightly to strongly elliptical, measured by their eccentricity (Ecc). Most orbits are tilted relative to their host body equator (Incl). Some orbit in the same direction as the primary's spin direction (prograde); some rotate in the opposite direction (retrograde).

The time it takes for the moon to make one orbit is the orbital period, measured in Earth days. Positive values for the period represent prograde motion; negative values represent retrograde motion.

NOTES: Data from Wikipedia, photos mostly NASA credits, via Wikipedia. "Orbit" is semi-major axis (distance from center of elliptical orbit to it's maximum elongation - equivalent to radius of a circle).

<== Buzz Aldrin, Apollo 11, Second man on the moon, June 1969.

Diameter (1 Km = 0.62 miles) and mass (1 Kg = 2.2 pounds) are measured or estimated by various means (orbit perturbations, brightness, period vs distance from host, space craft photos) and may not be very accurate in many cases. Diameter shown is maximum, if object has irregular shape.


 

"Discovery Order" is shown in Arabic numerals (eg 29) instead of Roman numerals (eg XXIX). Moons are often named by their order of discovery instead of their assigned names. For example, Jupiter XXIX is the 29th moon discovered at Jupiter, and is named Thyone, (pronounced Thigh-own-ee or Theee-oh-nee). It is the 30th moon of Jupiter, counting outward from the planet. As new moons are found, counter position may change, but the two names associated with each moon will not.
