Jupiter's famous Great Red Spot (GRS) is much trickier to spot than the Galilean moons. Space Telescope Science Institute Jupiter's neighborhood was always crowded, but the discovery of 12 new moons around the giant planet makes it more intriguing.

Astronomy 4 Observing Project 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 … • Pick one of the images where you can see all four moons and identify each one. Photographing Jupiter’s moons.
There are many interesting moons orbiting the planet, but the ones of most scientific interest are the first four moons discovered beyond Earth—the Galilean satellites. Adjust the time using your UT offset to determine the local time.

In addition, you need a good quality telescope of at least 4 inches aperture to see the GRS clearly. Jupiter’s largest moons are Ganymede and Callisto, both low-density objects that are composed of more than half water ice. A look at Jupiter's new moons. Although it's quite large, the feature's low contrast can make it hard to discern unless Jupiter is quite high above the horizon and the astronomical seeing is reasonably steady. Celestial Objects to Observe. Jupiter's largest moon, Ganymede, is larger than Mercury while the other three are larger than Pluto. The Galilean satellites are nearly spherical in shape due to their planetary mass, and so would be considered at least dwarf planets if they were in direct orbit around the Sun. It allows you to identify the four brightest moons at any given time. Adjust the time using your UT offset to determine the local time. The photos we took were acquired using a digital camera body (a FujiFilm X-M1) attached to a 66mm refractor. In addition, you need a good quality telescope of at least 4 inches aperture to see the GRS clearly. By: Gary Seronik and Adrian R. Ashford September 2, 2017. A sky chart program may be helpful in showing you the moons' positions at the time of your observations. Jupiter's famous Great Red Spot (GRS) is much trickier to spot than the Galilean moons.

• Find the orbital period of one of Jupiter' s moons using the images. Although it's quite large, the feature's low contrast can make it hard to discern unless Jupiter is quite high above the horizon and the astronomical seeing is reasonably steady. Of Jupiter's moons, eight are regular satellites with prograde and nearly circular orbits that are not greatly inclined with respect to Jupiter's equatorial plane. Combined, scientists now think Jupiter has 79 moons. Jupiter has 53 named moons and another 26 awaiting official names. Observing jupiter's moon with binoculars . The Galilean moons (or Galilean satellites) / ɡ æ l ɪ ˈ l iː ə n / 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 Jupiter in March 1610.
