The Moon will appear spectacular with a 50mm telescope, and you will be able to see the major craters and geological features. A blue filter can make the planet’s zones appear brighter. It is possible to detect its dark stripes (North and South Equatorial Belts) with a small scope. Jupiter can be seen with any telescope of any size. Jupiter has the most detailed surface of any celestial object, and it’s the closest thing we have to the Sun and Moon. The largest telescopes can show us Jupiter’s cloud bands and the Great Red Telescopes allow us to see Jupiter and its moons in great detail. The latest probe to visit the planet is Juno, which entered Jupiter’s orbit on July 4, 2016. In late February 2007, Jupiter was visited by the New Horizons probe, which used Jupiter as a gravitational slingshot to accelerate on its way to Pluto. Jupiter has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Voyager flyby missions of the 1970s. Ganymede, the largest of these, has a diameter greater than that of Mercury. Jupiter has at least 67 moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. The planet’s magnetic field is thought to be generated by electrical currents in this layer. Jupiter’s core is thought to be molten and may be surrounded by a thick layer of liquid metallic hydrogen. The temperature and pressure in the interior increase with depth, reaching values typical of the Sun’s interior by the time one-third of the way to the center. The interior of Jupiter is mainly composed of hydrogen and helium. A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the 17th century when it was first seen by telescope. The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interactions. Because of its rapid rotation, the planet’s shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium only composes about a tenth of the number of molecules in Jupiter. When viewed from Earth, Jupiter can be bright enough to cast shadows, and is on average the third-brightest natural object in the night sky after the Moon and Venus. The Romans named it after their god Jupiter. Jupiter has been known to astronomers since antiquity. It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. The giant planet will next come to opposition on November 3, 2023.Jupiter is the fifth planet from the Sun and the largest in the Solar System. Jupiter will be bright and beautiful for at least the next few weeks before rising earlier and earlier, and thus moving higher into the night sky. Look far to the right and you’ll see Saturn, whose incredible ring pattern is visible through any small telescope. Look just above Jupiter and you’ll also see a diamond-shaped constellation of four bright stars known as the “Great Square of Pegasus,” an asterism (unofficial shape) within a larger constellation. With any pair of binoculars or even a tiny telescope pointed at Jupiter you’ll see three or four of its large Galilean moons-Europa, Ganymede, Callisto and Io. The result of that is that it gets noticed much more than when it’s high in the sky during the middle of the night.īut take a closer look. Any planet near to its opposition is visible close to the horizon in the early evening when many people are still outside.
