For billions of years, Jupiter’s Trojan asteroids have orbited undisturbed, preserving chemical and physical clues from the ...

By 2020 over 7,000 Trojan asteroids had been discovered around Jupiter with two-thirds located around L4 and a third around L5. Astronomers estimate that between 1,800–2,200 of them have widths ...

These bits of cosmic flotsam and jetsam are the Jupiter Trojan asteroids. They follow heliocentric orbits with nearly the same semi-major axis as Jupiter, about 5.2 astronomical units.

Planetary scientists are keenly interested in the story of the Trojan asteroids. They suspect these objects are captured relics of our solar system's formation some 4 billion years ago.

The Trojan asteroids orbit the Sun in two main groups, one that leads ahead of Jupiter and another that follows behind. The first Trojan asteroid was spotted on February 22, 1906, by German ...

NASA’s Lucy spacecraft is on its way to Jupiter’s Trojan asteroids for a chance to get a closer look at the primordial rocks. But before its scheduled arrival at the Trojans in 2027, Buie and ...

Our #LucyMission just caught its first glimpse of its very-distant destinations, Jupiter’s Trojan asteroids, more than 330 million miles away. Lucy launched in 2021, yet won't fly by these ...

"With the discovery of 2019 UO14, all the gas giant planets are now known to have Trojan asteroids," he said. "Only Mercury and Venus still don't have known Trojans.". Saturn lags Jupiter in terms ...

Saturn seems to have snatched its first known Trojan asteroid, designated 2019 UO14, a few thousand years ago as the space rock was "bouncing" around the solar system.Additionally, because the ...

Item 1 of 5 NASA's Lucy spacecraft, atop a United Launch Alliance Atlas 5 rocket for a mission to study the Trojan asteroids in the outer solar system, launches from Pad-41 at Cape Canaveral Space ...

The Trojan asteroids are intriguing to astronomers because they are believed to be composed of raw materials left over from the formation some 4 billion years ago of our solar system’s giant ...

This fall, NASA is all about asteroids. OSIRIS-REx's brought samples from Bennu; Psyche will visit a space rock; and the Lucy spacecraft will fly by an asteroid.
