01 June 2020 Current Affairs: Astronomers have discovered a rare kind of space object. It is described as something between an asteroid and a comet. The object has been called an active asteroid. The celestial body was first noticed by the astronomers in June 2019 when the University of Hawaii’s Asteroid Terrestrial-impact Last Alert System (ATLAS) detected a faint new signal that appeared to be an asteroid in the Trojan group.
2019 LD: 2
♦ The newly discovered asteroid is named 2019 LD2.
♦ 2019 LD2 has an orbit like an asteroid but the tail of a comet.
♦ The specialty of 2019 LD2 special is that the active asteroid shares Jupiter’s orbit in an asteroid swarm known as the Jupiter Trojans.
♦ This is the first Jupiter Trojan that the astronomers have come across.
♦ These asteroids follow the same orbit like that of a planet. But. it remains 60 degrees ahead of or behind along the orbit.
♦ The Jupiter Trojan asteroids orbit the Sun in two huge swarms, one swarm orbiting ahead of the planet, where 2019 LD2 is present, and the other swarm orbiting behind it
♦ It is suspected that the Trojan asteroids have been captured into these orbits by Jupiter’s strong gravity.
♦ 2019 LD2 is a first-of-its-kind active asteroid because most Jupiter Trojans were captured billions of years ago.
♦ Other planets on the Solar system like Earth, Neptune, and Jupiter have more than one Trojan asteroids.
