The rotation of Jupiter's polar atmosphere is about five minutes longer than that of the equatorial atmosphere. [135] The planet is an oblate spheroid, meaning that the diameter across its equator is longer than the diameter measured between its poles. [85] On Jupiter, the equatorial diameter is 9,276 km (5,764 mi) longer than the polar ...
The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere. Astronomical bodies include stars, planets, dwarf planets and small Solar System bodies such as comets and minor planets (e.g., asteroids), as well as natural satellites and minor-planet moons.
Like Jupiter's South Pole, it has a bluer surface color than the rest of Jupiter. It was first imaged in July 2016 with the Juno probe entering the polar orbit of Jupiter. At the same time, its polar cyclone was discovered, measuring just over 3,000 km, surrounded by eight smaller cyclones which each measure 2,400–2,800 km in diameter.
It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup; [1] however, later studies revealed that icy satellites as large as Iapetus (1,470 kilometers in diameter) are not in hydrostatic equilibrium at this time, [2] and a 2019 assessment suggests that ...
The average distance between Neptune and the Sun is 4.5 billion km (about 30.1 astronomical units (AU), the mean distance from the Earth to the Sun), and it completes an orbit on average every 164.79 years, subject to a variability of around ±0.1 years. The perihelion distance is 29.81 AU, and the aphelion distance is 30.33 AU.
The north orbital poles of the Solar System major planets all lie within Draco. [1] The central yellow dot represents the Sun's rotation axis north pole. [citation needed] Jupiter's north orbital pole is colored orange, Mercury's pale blue, Venus's green, Earth's blue, Mars's red, Saturn's magenta, Uranus's grey, and Neptune's lavender.
Now, NASA has released a 3D infrared movie of Jupiter's north polar region, depicting the intense storms in the area, as well as the dynamo that powers the planet's massive magnetic field.
Approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's. The planets are not shown at the appropriate distance from the Sun.
