Jupiter is often able to capture comets that orbit the Sun; such comets enter unstable orbits around the planet that are highly elliptical and perturbable by solar gravity. While some of them eventually recover a heliocentric orbit, others crash into the planet or more rarely become one of its satellites. [2] [3]
The sky in the region was very overcast, so only an airborne observation team was able to successfully observe it falling above the clouds. It is now thought to be a remnant of the Lunar Prospector mission in 1998, and is the third time any previously unknown object – natural or artificial – was identified prior to impact.
Theia (/ ˈ θ iː ə /) is a hypothesized ancient planet in the early Solar System which, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris coalescing to form the Moon.
The best nights of all of 2022 to see Jupiter in the night sky are about to take place as the planet takes center stage in the night sky, a showing unlike any other in nearly six decades. The sun ...
Jupiter's moons were classified into four groups of four, based on their similar orbital elements. [204] This picture has been complicated by the discovery of numerous small outer moons since 1999. Jupiter's moons are divided into several different groups, although there are two known moons which are not part of any group (Themisto and Valetudo ...
The solar system's largest moon, Ganymede, which orbits the largest planet, Jupiter, was hit by an asteroid four billion years ago that shifted the gas giant's satellite on its axis, new research ...
Another spacecraft, Near-Earth Asteroid Scout, is loaded into NASA’s new moon rocket awaiting liftoff; it will use a solar sail to fly past a space rock that’s less than 60 feet (18 meters ...
A planet of Jupiter's mass still seems to provide increased protection against asteroids, but the total effect on all orbital bodies within the Solar System is unclear. This and other recent models call into question the nature of Jupiter's influence on Earth impacts. [52] [53] [54]
