NASA's Hubble spots comet with 400,000mile long tail lingering near Jupiter asteroids

Following Jupiter’s journey around the Sun are space rocks known as Trojan asteroids. These asteroids are some of the early remnants of the solar system and follow the same path as Jupiter around the Sun. Now, NASA’s Hubble Space Telescope has spotted a huge comet lingering near the asteroids.

It is the first time a comet has been seen taking its place in line with the Trojan asteroids.

NASA said: “After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way.

“The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter.

“This is the first time a comet-like object has been spotted near the Trojan population.”

Analysis from NASA revealed the comet belongs to a family called ‘Centaurs’.

Centaurs are icy bodies that live between the orbits of Jupiter and Neptune.

Scientists have called this particular one P/2019 LD2 (LD2) and have managed to track its orbit and future path.

LD2 came close to Jupiter two years ago, and it will come close again in another two years.

Bryce Bolin of Caltech in Pasadena, California, added: “Only Hubble could detect active comet-like features this far away at such high detail, and the images clearly show these features, such as a roughly 400,000-mile-long broad tail and high-resolution features near the nucleus due to a coma and jets

“The visitor had to have come into the orbit of Jupiter at just the right trajectory to have this kind of configuration that gives it the appearance of sharing its orbit with the planet.

“We’re investigating how it was captured by Jupiter and landed among the Trojans.

“But we think it could be related to the fact that it had a somewhat close encounter with Jupiter.”
