Moons versus Planet comparison chart
Edit this comparison chartMoonsPlanet
Fusion N/A Not often
Introduction (from Wikipedia) The Moon is Earth's only natural satellite. At about one-quarter the diameter of Earth (comparable to the width of Australia), [16] it is the largest natural satellite in the Solar System relative to the size of its planet. A planet, meaning "wandering star") is an astronomical object orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion
Temperature -280 F to 260 F It ranges from very cold to hot.
Size 2,159 miles only about one-tenth the size of a star
Life cycle This varies, but is from the time of formation to the time it leaves the orbit of its planet. For our moon, it will have a life span of approximately 20 billion years. Unlike stars of which we can observe millions in various stages of their "life cycle", planetary life cycles would be very speculative (hard to figure out)
Brightness 0.05 - 0.1 lux illumination not bright because it doesn't give off any light on its own
abundance N/A not very many (none like Earth have been discovered)
