Orbital periods and radius of galilean moons
Discovery As a result of improvements Galileo Galilei made to the telescope, with a magnifying capability of 20×, he was able to see celestial bodies more distinctly than was previously possible. This allowed Galileo to observe in either December 1609 or January 1610 what came to be known as the Galilean moons. On … See more The Galilean moons , or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of See more Fluctuations in the orbits of the moons indicate that their mean density decreases with distance from Jupiter. Callisto, the outermost and least dense of the four, has a density intermediate between ice and rock whereas Io, the innermost and densest moon, has a … See more All four Galilean moons are bright enough to be viewed from Earth without a telescope, if only they could appear farther away from Jupiter. (They are, however, easily distinguished with even low-powered binoculars.) They have apparent magnitudes between … See more Some models predict that there may have been several generations of Galilean satellites in Jupiter's early history. Each generation of moons to have formed would have spiraled into Jupiter and been destroyed, due to tidal interactions with Jupiter's See more Jupiter's regular satellites are believed to have formed from a circumplanetary disk, a ring of accreting gas and solid debris analogous to a See more GIF animations depicting the Galilean moon orbits and the resonance of Io, Europa, and Ganymede See more • Jupiter's moons in fiction • Colonization of the Jovian System See more WebGalilean Moons of Jupitercan only be done with observations when Jupiteris fairly high in the skyduring the lab period. It can be done without observations at any time, but it is educationally best with them. Since this is an observing lab, you should check the NWS weatherwell in advance of the lab night.

WebApr 9, 2024 · Although Jupiter has been known as a planet since the Ancient Chaldeans, Galileo Galilei’s first detailed observations were made in 1610 with a small telescope. In 1610, Galileo Galilei discovered four moons orbiting an object other than the sun or Earth: Io, Europa, Ganymede, and Callisto, also known as the Galilean moons. WebUse this to compute the orbital radii (R) of the moons’ orbits around Jupiter in kilometers. Convert the orbital period (P) that you measured for each moon from units of days to units of seconds. There are 60 60 24=86,400 seconds in a day. Io: Europa: Ganymede: Callisto: 5. Assume that the moons are on circular orbits (this is not a bad ...
