Scientist found a self-destructive asteroid with comet like tail
A new self-destructive asteroid has been recently discovered by scientists. This unusual asteroid which is called as Gault (6478) puffs out materials due to the speed at which it spins.
This asteroid is seen with two comets like tails the longer is 800,000 kilometers and shorter one 4,800 kilometers. The phenomenon of self-destruction takes place because of the pressure from the sunlight which increases the speed by 1 second in every 10,000 years. Scientists estimate the shedding has started 100 million years ago. This is called the YORP effect (Yarkovsky–O’Keefe–Radzievskii–Paddack,) the names of four scientists who contributed to the concept.
The asteroid is located in the asteroid belt, found in between the orbit of Mars and Jupiter. This self-destruction event is rare. “Active and unstable asteroids such as Gault are just now being detected because of new survey telescopes that scan the entire sky, which means asteroids that are misbehaving such as Gault cannot escape detection anymore,” said Olivier Hainaut, of the European Southern Observatory in Garching, Germany.
The first tail was not spotted by Hubble telescope in NASA instead it was discovered by the University of Hawai’i Institute for Astronomy (IfA) Asteroid Terrestrial-Impact Last Alert System (ATLAS) telescopes in Maunaloa and Haleakalā detected the first debris tail and the second shorter tail was seen through the Isaac Newton Telescope in Spain and later in the Canada–France–Hawaii telescope.
The scientist has found about 900 asteroids orbiting Earth around the sun, these are under close watch by various airspace research teams. If any of these fly too close to earth they will be redirected from its course so that it wouldn’t collide with earth. The collision could be so bad that it could wipe out an entire city and in case if this land in water bodies it could be strong enough to cause Tsunamis.
