For these reasons Jupiter has the highest frequency of impacts of any planet in the Solar System, justifying its reputation as the "sweeper" or "cosmic vacuum cleaner" of the Solar System. [7] 2018 studies estimate that between 10 and 65 impacts per year of meteoroids with a diameter of between 5 and 20 meters (16 and 66 ft) can occur on the ...
Jupiter would deliver about 36 Sv (3600 rem) per day to unshielded astronauts at Io and about 5.4 Sv (540 rems) per day to unshielded astronauts at Europa, [89] which is a decisive aspect due to the fact that already an exposure to about 0.75 Sv over a period of a few days is enough to cause radiation poisoning, and about 5 Sv over a few days ...
Hubble image of the scar taken on 23 July 2009 during the 2009 Jupiter impact event, showing a blemish of about 8,000 kilometres long. [ 1 ] In recorded history , the planet Jupiter has experienced impact events and has been probed and photographed by several spacecraft .
Before the comet was captured by Jupiter, it was probably a short-period comet with an aphelion just inside Jupiter's orbit, and a perihelion interior to the asteroid belt. [12] The volume of space within which an object can be said to orbit Jupiter is defined by Jupiter's Hill sphere. When the comet passed Jupiter in the late 1960s or early ...
It is around 0.64 times as massive and around 1.01 times as large as Jupiter. [3] This makes it very similar to Jupiter, in terms of mass and radius. [3] Illustration of the Kepler-90 system compared to the inner solar system. Kepler-90h is the outermost planet of the Kepler-90 system.
The European Space Agency's Jupiter Icy Moons Explorer (Juice) is amid its voyage to Jupiter with a scheduled 2031 arrival to study Ganymede and Jupiter's other moons, Callisto and Europa.
Beta Pictoris b is a super-Jupiter, an exoplanet that has a radius and mass greater than that of the planet Jupiter. It has a temperature of 1,724 K (1,451 °C; 2,644 °F), most likely due to its dusty atmosphere and mass (normally it would be much colder). It has a mass of between 9 and 13 Jupiter masses (M J), [5] and a radius of 1.46 R J. [2]
An anomalously high thermal flux, compared to the other Galilean satellites, was observed at an infrared wavelength of 10 μm while Io was in Jupiter's shadow. [41] At the time, this heat flux was attributed to the surface having a much higher thermal inertia than Europa and Ganymede. [ 42 ]
