Jupiter shown in the image 'Jupiter Marble' as recorded by Juno. 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]
^ Surface gravity derived from the mass m, the gravitational constant G and the radius r: Gm/r 2. ^ Escape velocity derived from the mass m, the gravitational constant G and the radius r: √ (2Gm)/r. ^ Orbital speed is calculated using the mean orbital radius and the orbital period, assuming a circular orbit. ^ Assuming a density of 2.0
Earth Gravity Field Anomalies, geoid format, NASA Earth Observatory Earth Geoid Field Anomaly globe, NASA Earth Observatory Mars free-air gravity map Venus gravity anomaly map. A gravity map is a map that depicts gravity measurements across an area of space, which are typically obtained via gravimetry.
Precisely map Jupiter's gravitational field to assess the distribution of mass in Jupiter's interior, including properties of its structure and dynamics. Precisely map Jupiter's magnetic field to assess the origin and structure of the field, and the depth at which the planet's magnetic field is created.
In classical mechanics, a gravitational field is a physical quantity. [5] A gravitational field can be defined using Newton's law of universal gravitation. Determined in this way, the gravitational field g around a single particle of mass M is a vector field consisting at every point of a vector pointing directly towards the particle. The ...
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.
Global image of Jupiter's moon Io acquired by Juno's JunoCam camera on 30 December 2023. The Juno spacecraft was launched in 2011 and entered orbit around Jupiter on July 5, 2016. Juno ' s mission is primarily focused on improving our understanding of Jupiter's interior, magnetic field, aurorae, and polar atmosphere. [88]
Gravity anomaly – Difference between ideal and observed gravitational acceleration at a location; Gravity of Mars – Gravitational force exerted by the planet Mars; Newton's law of universal gravitation – Classical statement of gravity as force; Vertical deflection – Measure of the downward gravitational force's shift due to nearby mass
