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 ...
Juno is a NASA space probe orbiting the planet Jupiter. It was built by Lockheed Martin and is operated by NASA 's Jet Propulsion Laboratory. The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 UTC, as part of the New Frontiers program. [ 6 ]Juno entered a polar orbit of Jupiter on July 5, 2016, UTC, [ 4 ][ 7 ...
In addition to its moons, Jupiter's gravitational field controls numerous asteroids that have settled around the Lagrangian points that precede and follow the planet in its orbit around the Sun. These are known as the Trojan asteroids , and are divided into Greek and Trojan "camps" to honour the Iliad .
Models. The most common base models to calculate the sphere of influence is the Hill sphere and the Laplace sphere, but updated and particularly more dynamic ones have been described. [2][3] The general equation describing the radius of the sphere of a planet: [4] where. is the semimajor axis of the smaller object's (usually a planet's) orbit ...
Ganymede, or Jupiter III, is the largest and most massive natural satellite of Jupiter, and in the Solar System. Despite being the only moon in the Solar System with a substantial magnetic field, it is the largest Solar System object without a substantial atmosphere. Like Saturn 's largest moon Titan, it is larger than the planet Mercury, but ...
The current model is that the moons experience tidal heating as a result of the gravitational field of Jupiter in inverse proportion to the square of their distance from the giant planet. In all but Callisto this will have melted the interior ice, allowing rock and iron to sink to the interior and water to cover the surface.
A gravity map is a map that depicts gravity measurements across an area of space, which are typically obtained via gravimetry. Gravity maps are an extension of the field of geodynamics. Readings are typically taken at regular intervals for surface analysis on Earth. [1] Other methods include analysis of artificial satellite orbital mechanics ...
The reason for the stability is a second-order effect: as a body moves away from the exact Lagrange position, Coriolis acceleration (which depends on the velocity of an orbiting object and cannot be modeled as a contour map) [22] curves the trajectory into a path around (rather than away from) the point.
