The 2009 Jupiter impact event, occasionally referred to as the Wesley impact, was a July 2009 impact event on Jupiter that caused a black spot in the planet's atmosphere. The impact area covered 190 million square kilometers, similar in area to the planet's Little Red Spot and approximately the size of the Pacific Ocean . [ 3 ]
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
English: Detail of Jupiter's atmosphere, as imaged by Voyager 1. Suggested for English Wikipedia:alternative text for images: This view of Jupiter's clouds with the Great Red Spot at top right as brown oval to right of wavy white and brown clouds. Below the Great Red Spot are various bands of bluer wavy clouds at smaller scales with smaller ...
In 2009, it was shown that the presence of a smaller planet at Jupiter's position in the Solar System might increase the impact rate of comets on the Earth significantly. 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.
Chiron, a moon of Saturn supposedly sighted by Hermann Goldschmidt in 1861 but never observed by anyone else.; Chrysalis, a hypothetical moon of Saturn, named in 2022 by scientists of the Massachusetts Institute of Technology using data from the Cassini–Huygens mission, thought to have been torn apart by Saturn's tidal forces, somewhere between 200 and 100 million years ago, with up to 99% ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
The Titan’s wreckage was seen for the first time in pictures after the Coast Guard announced on Thursday (23 June) that ROVs (remotely-operated vehicles) found its chambers in a sea of debris 1 ...
This is a list of the projected landing zones on extraterrestrial bodies. The size of the ellipse or oval graphically represents statistical degrees of uncertainty, i.e. the confidence level of the landing point, with the center of the ellipse being calculated as the most likely given the plethora of variables.
