Document Summary
A: kepler believed there was an undiscovered planet in the large space. Bodes law was a numerical trend that he applied to the orbits of the planets; however there was one value (2. 8u) in between mars and jupiter which did not apply to a planet. A: uranus" orbit was seen to deviate from its usual nearly circular path; so it was believed that there was a planet beyond uranus that was causing the deviation due to its gravitational pull. A: by observing each planet"s moon they could use kepler"s laws to determine their respective masses. They are more massive than the other planets but when comparing the mass to their size they are not very dense. A: current theory after the sun was born from a spinning, collapsing gas cloud, the remaining gaseous and rocky particles in the sun"s spinning circumstellar disk coalesced/merged into planets.
