For more than three years the structure of cyclones at both poles of the nearest to us gas giant remained stable, but on November 3, 2019, on the 22nd rotation, "Juno" found the birth of a new cyclone at the South Pole: it quickly "pushed" the previous (although still has a smaller size, about 800 km), and now the centers of peripheral cyclones ...
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). [ 122 ]
The negative pole is the pole toward which the thumb points when the fingers of the left hand are curled in its direction of rotation. This change was needed because the poles of some asteroids and comets precess rapidly enough for their north and south poles to swap within a few decades using the invariable plane definition.
The north pole is that pole of rotation that lies on the north side of the invariable plane of the Solar System (near the ecliptic). The location of the prime meridian as well as the position of the body's north pole on the celestial sphere may vary with time due to precession of the axis of rotation of the planet (or satellite).
The south pole star is Delta Doradus. Mars: The top two stars in the Northern Cross, Sadr and Deneb, point to the pole. [26] Markeb is a couple of degrees away. Jupiter: a little over two degrees away from Aldhibah: about two degrees north of Delta Doradus: Saturn: in the far northern region of Cepheus, about six degrees from Polaris: Delta ...
Jupiter's Great Red Spot (GRS) is an elliptical shaped anticyclone, occurring at 22 degrees below the equator, in Jupiter's southern hemisphere. [39] The largest anticyclonic storm (~16,000 km) in our solar system, little is known about its internal depth and structure. [ 40 ]
The positive pole of a planet is defined by the right-hand rule: if the fingers of the right hand are curled in the direction of the rotation then the thumb points to the positive pole. The axial tilt is defined as the angle between the direction of the positive pole and the normal to the orbital plane.
