If Io did have a sub-surface ocean of magma, the moon would deform under Jupiter's gravity by a significant amount. However, the Doppler measurements suggest that Io is pretty rigid, which means ...

If a person with a mass of 55kg was to travel to Jupiter or Pluto, the effects of gravity would be very different from those on Earth. Gravity is the pull that a planet exerts towards its centre.

Getting from Earth to space isn’t just about speed—it’s about planning the right trajectory. The Moon, our closest neighbor, ...

Gravity assists have become common practice for spacecraft venturing to the far reaches of our solar system. For instance, last year, the European Space Agency's Jupiter Icy Moon Explorer (JUICE ...

Objects under the influence of a gravitational field will move toward the field's center of gravity. Sometimes, as with the Sun and Jupiter, their mutual center of gravity or barycenter lies ...

For centuries, Jupiter reigned as king of the moons. Initially, the Big Four, discovered by Galileo, and then as optics and astronomy advanced, more and more, smaller and smaller bodies, until Big J ...

After that it should be smooth sailing out to Jupiter. The Europa Clipper is packed with a total of nine instruments (including radars, magnetometers, sensors, a thermal instrument, and a gravity ...

After that, it's a straightforward trek to the outer solar system; the probe is set to arrive at Jupiter's orbit in April 2030. "We come in very fast, and the gravity from Mars acts on the ...

Using data collected by NASA's Juno spacecraft as it flew past Jupiter's highly volcanic moon ... above the surface of Mars for what's known as a gravity assist—a maneuver to bend the ...
