Although the impacts took place on the side of Jupiter hidden from Earth, Galileo, then at a distance of 1.6 AU (240 million km; 150 million mi) from the planet, was able to see the impacts as they occurred. Jupiter's rapid rotation brought the impact sites into view for terrestrial observers a few minutes after the collisions. [34]
The Gravity Science experiment and instrument set aboard the Juno Jupiter orbiter is designed to monitor Jupiter's gravity. [1] [2] [3] It maps Jupiter's gravitational field, which will allow the interior of Jupiter to be better understood. [3] It uses special hardware on Juno, and also on Earth, [1] including the high-gain K-band and X-band ...
At one point, the two may fall into sync, at which time Jupiter's constant gravitational tugs could accumulate and pull Mercury off course, with 1–2% probability, 3–4 billion years into the future. This could eject it from the Solar System altogether [1] or send it on a collision course with Venus, the Sun, or Earth. [10]
Io's shape changes as it completes its orbit. (C) Earth's moon's orbit is actually more eccentric than Io's, but Earth's gravity is much weaker than Jupiter's, so Earth's moon does not experience as much deformation. [1] Tidal heating of Io (also known as tidal working) occurs through the tidal friction processes between Jupiter and its moon ...
Entering a Hohmann transfer orbit from Earth to Jupiter from low Earth orbit requires a delta-v of 6.3 km/s, [170] which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit. [171] Gravity assists through planetary flybys can be used to reduce the energy required to reach Jupiter.
In astrophysics, gravitational compression is a phenomenon in which gravity, acting on the mass of an object, compresses it, reducing its size and increasing the object's density. In the core of a star such as the Sun, gravitational pressure is balanced by the outward thermal pressure from fusion reactions, temporarily halting gravitational ...
Gravity well is a metaphorical name for the sphere of influence, highlighting the gravitational potential that shapes a sphere of influence, and that needs to be accounted for to escape or stay in the sphere of influence.
The Jupiter mass, also called Jovian mass, is the unit of mass equal to the total mass of the planet Jupiter. This value may refer to the mass of the planet alone, or the mass of the entire Jovian system to include the moons of Jupiter. Jupiter is by far the most massive planet in the Solar System. It is approximately 2.5 times as massive as ...
