Document Summary
Lunar eclipses can only occur at full moon. Stars can die quietly or with great fanfare as in supernovae explosions. This releases processed material back into the interstellar medium for re-use into new stars and planetary systems. Theoretical abundance of elements from nuclear fusion matches observations very well. Dwarf planets, asteroids, and comets are also very common components in the solar. All resemble very small terrestrial planets with comets having a higher volatile material (gases) content that allow them to develop beautiful tails. The formation of our solar system is best described by the nebula theory. As a theory, it continues to evolve as new data leads to updates and modifications. Relatively high densities, rock and metals composition. Orbit close to the sun (warmer surfaces) Relatively low densities, mostly gaseous composition (hydrogen, helium, hydrogen compounds) Orbit further from the sun (colder surfaces) Circular orbits in same direction as planet rotation. Far more numerous than the medium and large moons.
