![]() An 8x42 binocular or 9x50 finderscope will easily reveal the four Galilean moons. But they also offer celestial coordinates, a real-time sky map, rise and set times, and physical and orbital parameters.Īny small telescope with an aperture of 60mm to 90mm can reveal Jupiter's four brightest moons and the planet's cloud belts and zones. Apps like SkyPortal provide a wealth of information at your fingertips, including audio and written descriptions about Jupiter. Seven have flown by, while two have orbited the planet.Īstronomy apps such as Celestron's SkyPortal Powered by SkySafari™ mobile app (included with the purchase of any Celestron telescope) are the easiest and most modern way to help locate and learn about celestial objects. Nine spacecraft have visited Jupiter since the early 1970s, with Pioneer 10 being the first and Juno being the latest (2016).Wind speeds above 360 miles per hour are not uncommon. These weather fronts can exhibit wind speeds about twice as fast as the strongest hurricanes on Earth. Storms and winds on Jupiter are extremely wicked.They consist of tiny particles due to collisions between Jupiter's moons and meteorites. Its rings are very faint and cannot be seen in amateur telescopes. Discovered in 1979 by NASA's Voyager 1 spacecraft, Jupiter has rings, but unlike Saturn's ring system, it is much smaller.Each has its unique characteristics: Io is covered in hundreds of active volcanoes, Europa may have a water ocean that exists beneath its surface that could harbor life, Ganymede is the largest moon in the Solar System, and Callisto might also have an ocean buried deep beneath its icy surface. The Italian astronomer Galileo Galilei discovered the four largest - Io, Europa, Ganymede, and Callisto in 1610 and are known as the Galilean Satellites.Scientists estimate between 80 and 95 moons orbiting the planet and counting!.About 11 Earths placed side-by-side would match the diameter of Jupiter.1,300 Earths could easily fit inside Jupiter by themselves. It is so big that all the planets in the Solar System could fit inside Jupiter if it were hollow. Jupiter is 318 times more massive than the Earth.Trapped charged particles form radiation belts like Earth's Van Allen belts but are much more dangerous and intense. Its magnetic field is a million times the volume of Earth's magnetosphere. Jupiter boasts the strongest planetary magnetic field in the entire Solar System.One day on Jupiter is only 10 Earth hours long! Jupiter orbits around the Sun approximately every 12 years at an average speed of 29,236 miles per hour. Jupiter is the fastest-rotating planet in the Solar System.However, Jupiter is not massive enough to ignite a fusion reaction at its core to become a star. ![]() Its composition is 90% hydrogen and 10% helium-similar to the Sun.
