"Composed mostly of water ice with embedded dust particles, comets originally formed in the cold outer planetary system while most of the rocky asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter", the agency added. As NASA failed to detect the asteroid, Davide Farnocchia, a scientist at NASA's Center for Near-Earth Object (NEO) Studies revealed that the space agency is not tracking smaller asteroids like 2019 MO as they are very small, and it will not pose any kind of threats to the planet.
It is noteworthy that NASA representatives said the facility in 2019 once, in that moment, when he was at a distance of 500,000 kilometers from Earth - farther than the orbit of our moon.
CNEOS representatives confirmed on August 15 that QV89 was no threat to Earth, and that the asteroid would instead rocket past our planet on September 27 "at a comfortable distance of 4.3 million miles (6.9 million km), about 18 times the distance of the Moon".
The approaching asteroid has been identified by CNEOS as 2019 GT3. "And since the quantity of heat that absorbs, the asteroid, is associated with such things as it is, what it consists of, the Sun's influence on the trajectory of these cosmic bodies are virtually impossible to predict".
It will be at a speed of 14,361 mph and is now about 3.3 million miles from Earth. It is estimated to have a diameter of 1,247 feet.
Though QZ3 is the biggest asteroid, it is also the furthest from Earth, at a distance of approximately 2.3 million miles from our planet, CNEOS reported.
The asteroid in question is called '2019 OK, ' and when it was first found, it was not classed as an asteroid near-Earth.
CNEOS classified 2019 RH as an Apollo asteroid.
In other words, at its closest, the asteroid will safely miss us from a distance of 3.3 million miles (5.3 million km). During this time, the asteroid is expected to be about 0.26621 astronomical units or roughly 25 million miles away from the planet's center.
NASA defines all PHAs as asteroids 500ft (150m) or larger on potentially threatening close approaches to Earth.
Space agencies are keeping an eye on Near Earth Objects passing close to Earth but even their methods aren't full proof.
The photograph of the situation told: Earth is headed directly by a huge asteroid from space, as big as it had affected 4 billion years earlier.
