Jupiter

Jupiter is the largest planet in the Solar System, with a volume that could fit more than 1300 Earth-sized planets. It appears in the night sky as a very bright, yellowish-white point that can easily be seen with the naked eye. The planet is enveloped by a massive atmosphere, divided into light and dark bands that are visible through a small telescope. Detailed images from large telescopes and space probes reveal enormous atmospheric swirls — gigantic storms often larger than the entire Earth. Jupiter, along with Saturn, belongs to the class of planets known as gas giants. These planets do not have a solid surface. Jupiter's atmosphere, composed mainly of hydrogen and helium, gradually thickens with depth and transitions into a liquid mantle of molecular hydrogen. This then converts into metallic hydrogen, which behaves in a manner similar to molten metal. At the center lies a very hot core composed of liquid rock and iron. Jupiter is also surrounded by a faint ring system and more than 60 moons orbit the planet. The four largest moons, known as the Galilean moons, are visible with small binoculars.
