Olivier Hainaut from the European Southern Observatory in Garching discovered this bizarre cosmological body called Gault. He said, "This event of self-destruction is rare. Active and unstable asteroids like Gault are just being recognized by new survey telescopes that scan all over the sky, which means bad-looking asteroids like Gault can no longer escape recognition.
Images from the Hubble Space Telescope show two narrow comet-like tails of dusty debris streaming from the Gault asteroid (6478).
Each tail represents an episode in which the asteroid discarded its material.
Gault decays strongly associated with a rare process known as the YORP effect.
The acronym YORP stands for "Yarkovsky-O & # 39; Keefe-Radzievskii-Paddack", the names of four scientists who contributed to the concept

The concept describes how sunlight heats an asteroid, with the resulting infrared radiation exiting its heated surface The face generates a rotational impulse.
The process creates a tiny torque that causes the asteroid to continuously accelerate
When the resulting centrifugal force begins to overcome gravity, the surface of the asteroid becomes unstable and landslides can cause dust and debris drifting into space at a couple miles per hour or the speed of a walking human.
The researchers estimate that Gault has been spinning slowly for more than 1
NASA stated that there are 900 asteroids more than one kilometer in diameter orbiting the earth around the sun, while the largest is nearly 34 kilometers wide.
The US Space Agency and agencies from other countries catalog and track space objects.
According to NASA, if at all If he drives too close to Earth, a space campaign will be launched to distract the object.
One of the "asteroid hunters" said there might be space rocks that they do not know A threat to the Earth.
