Jupiter trojan - Wikipedia
The Jupiter trojans, commonly called trojan asteroids or simply trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each trojan librates around one of Jupiter's stable Lagrange points: either L 4, existing 60° ahead of the planet in its orbit, or L 5, 60° behind.

Sep 12, 2018 · In 2021, NASA will launch the Lucy mission, which will investigate two primitive asteroid populations that congregate at stable points along Jupiter’s orbital path. By getting a closer look at...
Impact events on Jupiter - Wikipedia
The direct observation of impact events on Jupiter has led to the growing awareness, even in public opinion, of the potentially devastating consequences of an impact of a comet or asteroid with Earth.
How Were the Trojan Asteroids Discovered and Named? - NASA
Feb 22, 2021 · As Jupiter moved, this asteroid remained ahead of Jupiter, as though it was somehow trapped in Jupiter’s orbit around the Sun. German astronomer Adolf Berberich observed that the asteroid was nearly 60 degrees in front of Jupiter.

Nov 3, 2024 · Introduction. Most asteroids can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest asteroid at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth’s Moon.

[2312.02325] A Crater Chronology for the Jupiter's Asteroids
Dec 4, 2023 · We present a new crater chronology for Jupiter's Trojan asteroids. This tool can be used to interpret the collisional history of the bodies observed by NASA's Lucy mission. The Lucy mission will visit a total of six Trojan asteroids: Eurybates, Polymele, Orus, Leucus, and the near equal mass binary Patroclus-Menoetius.
