This is the first Jupiter Trojan astronomers have ever seen spewing out gas as a comet would. Researchers using the University of Hawaii’s Asteroid Terrestrial-impact Last Alert System (ATLAS) have found (via Gizmodo) a Trojan asteroid, 2019 LD2, that not only follows an odd orbit ahead of Jupiter but also sports an icy tail — it’s a unique “crossover” between asteroid and comet. The gas giant has two massive swarms of asteroids along its orbital path, one out front and one behind. Firstpost - All Rights Reserved. It is rare to find active asteroids but the discovery of an active Jupiter Trojan asteroid is “extraordinary”, according to the university. The second theory is that LD2 was a stray asteroid 2 captured by Jupiter from further out in the solar system where it is cold enough for ice to remain on the surface. Picture: ATLAS/A. The asteroid is believed to be the first-of-its-kind. A GROUP of 19 "alien" asteroids lurking between Jupiter and Neptune may have come from another star system, according to scientists. 3200 Phaethon / ˈ f eɪ. The Minor Planet Center designated the new discovery as 2019 LD2. Putin said to have 2 identical offices: 1 in Moscow, the other at the beach Astronomers searching space for asteroids that may pose threats to Earth have discovered a “first-of-its-kind” object near Jupiter’s orbit. Trojan Asteroid Spotted Near Jupiter's Orbit for the First Time in Billion Years Image for representation Known as active asteroids, these objects appear to be asteroids at first, but later develop activity, such as tails, like that of comets. Should Forsaken be Forgiven? According to the reports, the Institute for Astronomy at the University of Hawaii's Asteroid Terrestrial-impact Last Alert System (ATLAS) has revealed that they have found a new asteroid with a comet-like tail orbiting in the same path used by Jupiter to revolve around the sun. The asteroid belt is located between the orbits of Jupiter and Mars. Astronomers said in … ATLAS has shown that the predictions of their icy nature may well be correct,” said Alan Fitzsimmons. NASA scientist from the Jet Propulsion Laboratory, Dr Kevin Hand, says Europa is one of the most likely places to find alien life within our solar system. “We have believed for decades that Trojan asteroids should have large amounts of ice beneath their surfaces, but never had any evidence until now. NASA is preparing to fly to Jupiter within the next decade to better understand the planet and investigate one of its icy moons, Europa. All times AEDT (GMT +11). Active asteroids are small Solar System bodies that have asteroid-like orbits but show comet-like visual characteristics i.e., they show comae, tails, or other visual evidence of mass-loss (like a comet), but their orbit remains within Jupiter’s orbit (like an asteroid). It is also possible it could have suffered a landslide or an impact from another asteroid, exposing ice that used to be buried under layers of protective rock. 1Up In The House | Team24 takes another Chicken Dinner? NASA's OSIRIS-REx mission arrived at near-Earth asteroid Bennu a year ago, and the spinning top-shaped space rock has been full of surprises. In December 2019, a group of astronomers had put in a request to take a closer look at the heavenly body using the Spitzer Space Telescope. However, New type of Trojan asteroid discovered near Jupiter has an orbit like an asteroid but the tail of a comet, OPPO Reno5 Pro 5G is a Fierce Videography Marvel That Will Unleash a World of Infinite Possibilities, Tata Altroz iTurbo launched in India at a starting price of 7.73 lakh, LG is likely to exit the smartphone market in 2021: All we know so far, Harman launches JBL TWS C115 earphones with 21-hours battery life at Rs 4,999, Amazon beauty presents Vanity Diaries. Early in June 2019, ATLAS reported what seemed to be a faint asteroid near the orbit of Jupiter. At about 588 miles across, it’s about the third … Picture: JD Armstrong/IfA/LCOGTSource:Supplied. “It’s a real bonus for ATLAS to make these kinds of discoveries.”, ATLAS image of asteroid 2019 LD2 from late June 2019. While not entirely unknown, what makes 2019 LD2 special is that it shares Jupiter’s orbit in an asteroid swarm known as the Jupiter Trojans. Astronomers spot a strange, first-of-its-kind asteroid near Jupiter Jon Fingas 5/24/2020. While the active asteroid sample size remains small, the evidence for an astonishing diversity of ... are called Jupiter family comets and are thought to originate in the Kuiper Belt. There are two theories as to why LD2 is active and among the Jupiter Trojans. Of the roughly 800,000 known asteroids between Mars and Jupiter, astronomers estimate that this type of event in the asteroid belt is rare, occurring roughly once a year. Astronomers also detailed that the newly found Jupiter Trojan has only been active for less than a year, suggesting that Jupiter may have captured the asteroid from a distant colder orbit. Researchers using the University of Hawaii’s Asteroid Terrestrial-impact Last Alert System (ATLAS) have found (via Gizmodo) a Trojan asteroid, … The space object found is the first that emits gas just like a comet. These are usually called Trojan asteroids but it is the first one of its kind to be seen with a comet-like-tail. However, the newly discovered asteroids are located between Jupiter and Neptune, … “The asteroid passed behind the Sun and was not observable from the Earth in late 2019 and early 2020, but upon its reappearance in the night sky in April of 2020, routine ATLAS observations confirmed that it still looks like a comet. Astronomers have discovered a “first-of-its-kind” object near Jupiter’s orbit, which appears to be a cross between an asteroid and a comet. These bodies were originally designated main-belt comets (MBCs) in 2006 by astronomers David Jewitt and Henry Hsieh, but this name implies they are necessarily icy in composition like a comet and that they only exist within the main-belt, whereas the gro… A. Saturn B. Mars C. Neptune D. Jupiter ə θ ɒ n / (previously sometimes spelled Phaeton), provisional designation 1983 TB, is an active Apollo asteroid with an orbit that brings it closer to the Sun than any other named asteroid (though there are numerous unnamed asteroids with smaller perihelia, such as (137924) 2000 BD 19). iv.It was observed to be between an asteroid and a comet and was called an active asteroid.

The Institute for Astronomy at the University of Hawaii has revealed that a new asteroid with a comet-like-tail has been discovered moving in the same orbit travelled by Jupiter around the sun. The object is 2.5 to 5.5 miles (4 to 9 km) wide, and it’s located in the main asteroid belt, between the orbits of Mars and Jupiter. A rare kind of space object, which is something between an asteroid and a comet, has been discovered by astronomers.
