Jupitors io moon energy source9/3/2023 It is now known if Jupiter has a core and recent analysis suggests that the atmosphere extends up to 3.000 km / 1.864 mi down, and beneath this is an ocean of metallic hydrogen going all the way down to the center.Sadly, they can only be seen through ultraviolet. The combination of the powerful magnetic field and the charged particles in the plasma torus creates the brightest auroras in the solar system.The charged particles also come from Io’s volcanic activity. It is a field of extremely charged particles making it difficult for a spacecraft to approach the planet, yet some zones are a bit safer. Jupiter is surrounded by a plasma torus, produced by its strong magnetic field.It has been observed since 1830, and it is active for hundreds of years. A distinct feature of Jupiter is its Great Red Spot – a persistent high-pressure region in the atmosphere that produces an anticyclonic storm, the largest in the solar system.It produces almost a million Megawatts – Earth’s aurora produces about 1.000 Megawatts. As a result, the aurora of Jupiter is stronger as well.It has a very strong magnetosphere, almost 20 times stronger than Earth’s magnetic field and 20.000 times larger.They are mostly made up of dust and small rocky pieces. Jupiter has 3 ring systems though they are fainter and smaller than Saturn’s.Among these satellites, four of them are quite famous: Io – for its volcanic activity, Ganymede – for its size, being the largest known moon of any planet, Europa – for hosting favorable conditions to find present-day environments suitable for some form of life beyond Earth, and Callisto – that may also host a subsurface ocean.Jupiter currently has only 79 known satellites. Though it remains the biggest planet, Jupiter has been dethroned as the moon king by Saturn, which now has 82 moons.It holds a unique place in the history of space exploration since after it was observed through the telescope, some of its moons were also discovered and because of this, their movements were observed thus ending the belief that everything orbited the Earth.Jupiter’s atmosphere is the largest planetary atmosphere in the solar system. A very small fraction of the atmosphere is made up of compounds such as ammonia, sulfur, methane, and water vapor.Jupiter does not have a solid surface being comprised mostly out of swirling gases and liquids such as 90% hydrogen, 10% helium – very similar to the sun.Since Jupiter has a small axial tilt of only 3.13 degrees, it has little seasonal variations.A Jovian year is about 12 Earth years, quite long in comparison to its short days.Jupiter rotates once every 10 hours – A Jovian day - thus it has the shortest day of all the planets in the solar system.Its powerful gravity has been used to hurl spacecraft into the farthest regions of the solar system. The gas giant has a gravity of 24.79 m/s², a little more than twice of Earth.Jupiter is also twice as massive as all the other planets combined, having 318 times the mass of Earth.It is the biggest planet of the Solar System, with a mean radius of 43.440 miles / 69.911 km, a diameter at the equator of about 88.846 mi / 142.984 km, and at the poles, the diameter is only 83.082 mi / 133.708 km.Its exact position can be checked online since the planet is constantly tracked. Jupiter is one of the five visible planets (Mercury, Venus, Mars, Saturn), being the fifth most distant from the Sun at an average distance of 5.2 AU, its closest approach is at 4.9 AU and at its farthest 5.4 AU.Jupiter is named after the principal Roman god, the equivalent of the Greek god Zeus. Since many cultures observed Jupiter, they all gave it different names but the Roman name remained used in the majority of cultures.However, the first telescopic observations were conducted by Galileo Galilei in 1609 and in 1610 Galileo also discovered the major moons of Jupiter, but of course not the smaller ones. Since it is the fourth brightest object in the sky, Jupiter was observed since ancient times and thus no one can be credited for its discovery.
