Io, Europa, Ganymede and Callisto-the so-called Galilean satellites-were seen by the Long Range Reconnaissance Imager on the New Horizons spacecraft during its flyby of Jupiter in late . [72] With a mission extension, Juno has since begun close flybys of the Galileans starting with Ganymede in 2021 followed by Europa in 2022 and planned flybys of Io in late 2023 and 2024. In collaboration with Chadwick Trujillo and David Tholen, Sheppard continued surveying around Jupiter from 2016 to 2018 using the Cerro Tololo Observatory's 4.0-meter (13ft) Vctor M. Blanco Telescope and Mauna Kea Observatory's 8.2-meter (27ft) Subaru Telescope. Jupiter has numerous moons, which make the Jovian system much like a miniature solar system. Jupiter has the second largest number of moons with reasonably stable orbits of any planet in the Solar System.. The other moons are much smaller, with the least massive Galilean moon being more than 7,000 times more massive than the most massive of the other moons. Voyager 1 - NASA Mission to Jupiter and Saturn (1977) Voyager 2 - NASA Mission to Jupiter, Saturn, Uranus, Neptune, and beyond (1977) Pioneer 11 - NASA Jupiter flyby (1973) Pioneer 10 - NASA Jupiter flyby (1972) Future Missions. The work, published July 12 in Nature Astronomy, estimates that the surface of Europa has been churned by small impacts to an average depth of about 12 inches (30 centimeters) over tens of millions of years. But in recent years several dozen tiny moons in various orbits farther out have been detected. 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: Io, Europa, Ganymede, and Callisto. For comparison, the area of a sphere with diameter 250km is about the area of, Diameters with multiple entries such as "604034" reflect that the body is not a perfect, The only satellites with measured masses are Amalthea, Himalia, and the four Galilean moons. Metis is the closest moon to Jupiter at a distance of 128,000 km. Juno zoomed past icy Ganymede on Monday, passing within 645 miles (1,038km). Image: NASA / Galileo Mission. The irregular captured moons are shaded light gray and orange when prograde and yellow, red, and dark gray when retrograde. NASA-funded scientists have discovered shaded locations within pits on the Moon that always hover around a comfortable 63 F. To most of us, dust is an annoyance.
