The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
Jupiter's magnetic field is the strongest of any planet in the Solar System, [102] with a dipole moment of 4.170 gauss (0.4170 mT) that is tilted at an angle of 10.31° to the pole of rotation. The surface magnetic field strength varies from 2 gauss (0.20 mT) up to 20 gauss (2.0 mT). [123]
Jupiter has the strongest and biggest magnetic fields known to exist in the solar system. [6] Studying these fields is one of the goals of the Juno mission, and in particular the task rests on the Magnetometer instruments. MAG measures the field about 60 times per second, and records the direction and strength of the field. [6]
The existence of Jupiter's magnetic field was first inferred from observations of radio emissions at the end of the 1950s and was directly observed by the Pioneer 10 spacecraft in 1973. The main driver of Jupiter's magnetosphere is the planet's rotation. In this respect Jupiter is similar to a device called a Unipolar generator. When Jupiter ...

In 2014, a magnetic field around HD 209458 b was inferred from the way hydrogen was evaporating from the planet. [20] [21] In 2019, the strength of the surface magnetic fields of 4 hot Jupiters were estimated and ranged between 20 and 120 gauss compared to Jupiter's surface magnetic field of 4.3 gauss.
From May 25, 2024 to June 9, 2025, the expensive planet Jupiter will be transiting the sign of Gemini for the first time in 12 years. Jupiter will stay in the air sign for the next 12 months ...
Where the solar wind intersects with a planet that has a well-developed magnetic field (such as Earth, Jupiter or Saturn), the particles are deflected by the Lorentz force. This region, known as the magnetosphere , causes the particles to travel around the planet rather than bombarding the atmosphere or surface.
