Io has been studied by spacecraft from Pioneer 10 and 11 in 1973 and 1974, all the … Using Kepler's 3rd Law for Jupiter's Moons. To do so, we divide all periods by the period for Io, P = 1.769 days and all orbital sizes by the orbital size for Io, a = 421,600 km. As time goes by, the moons will move about Jupiter. ? The moons appear to be lined up because we are looking edge-on to the orbital plane of the moons around Jupiter.
The Galilean Moons Each of the Jovian planets has a number of moons, although Jupiter has the most with more than 60 catalogued to date. The moons of Jupiter are listed below by orbital period.
For those wondering: Io takes 1.8 days, Europa 3.6, Ganymede 7.2 and Callisto 16.7 days to fully orbit Jupiter. The moons of Jupiter are listed below by orbital period. The labels indicate the ratios of orbital periods: Europa's is twice Io's, and Ganymede's is four times Io's. Source: NASA/Cornell University. Moons massive enough for their surfaces to have collapsed into a spheroid are highlighted in bold. Nereid has a long orbital period, but there are others with longer periods, for example Phoebe, a moon of Saturn. Doing some of them ahead of lab period would be helpful. Although Kepler's 3rd Law is called the 3rd Law of Planetary Motion, this formula can be applied to the moons of Jupiter as well.The 3 innermost Galilean moons - Io, Europa and Ganymede - are locked into an 4:2:1 orbital resonance. Let's break it down: Orbital period is the amount of time it takes an object to go all the way around whatever it is gravitationally bound to (orbiting). Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above. For the Earth (which, as you know, is gravitationally bound to the Sun) it takes one year (365 days) to complete one orbit--this is Earth's orbital period. Kepler's 3rd law for a fixed center of force (e.g., Jupiter for the moons of Jupiter) can always be written p**2 ∝ r**3, where p is orbital period and r is mean orbital radius. Io, the closest of the Galilean Moons has the fastest revolution with an orbital period on only 42.5 hours. The four inner moons are much smaller, the fourth most massive being more than 7000 times more massive than the fifth-most. A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. Determining the Periods of Jupiter’s Four Galilean Moons Project Write-Ups due on Wednesday, 4 May, by 5 p.m. Introduction: When on 7 January 1610 Galileo turned his telescope toward Jupiter, he observed several small points of light close the planet, lined up on a straight line through Jupiter’s center. Some of the Tasks can be completed ahead of the lab period. The physical and orbital characteristics of the moons vary widely. Io, the closest of the Galilean Moons has the fastest revolution with an orbital period on only 42.5 hours. Answer to Orbital Periods of the Galilean Moons First of all, open the program JupSat95 www.ualr.edu/mxseigar/jupiter/?
The moons of Jupiter are listed below by orbital period. Orbital Periods: Io: 1.8 days Europa: 3.6 days (exactly 2 times Io's period!) Callisto is almost part of this, and will eventually get locked into a resonance with 8 … Orbital resonances of the Galilean moons of Jupiter Animation of the 1:2:4 Laplace resonance between Ganymede, Europa, and Io. Galilean Moons orbits over 2 hours [OC] ... Granted, you can see Io’s motion the easiest, but the difference in orbital periods means the others don’t move nearly as much in the same timeframe. From the appearance of your graph do you think there is a correlation between distance from Jupiter and orbital period. It is probably best to print out a copy of Report Form on the lab room printer when you get to the lab room since updates to the report forms are ongoing. These are the four Galilean moons, which are comparable in size to the Moon. Moons massive enough for their surfaces to have collapsed into a spheroid are highlighted in bold. The Ultimate List of All Moons of Jupiter [All 79 Explained] ... Orbital Period: 7 hours 10 minutes; Mass: 3.6 × 10 16 kg; Surface Temperature: 123K ; Surface Gravity: – 2] Adrastea. This is also known as the orbital period.
The X-values should be the radius of the orbit in units of thousands of kilometers (e.g.
