Asteroids have become top billing in news ever since it was first surmised that one such space rock had caused the demise of the dinosaurs. However, did you know that asteroids are sometimes called minor planets? According to NASA, asteroids are rocky parts that were left from the early formation of our solar system about 4.6 billion years ago. The size of the asteroids ranges from 530 km in diameter to 10 m. These space rocks are usually observed in the main asteroid belt between the orbits of Mars and Jupiter. However, there is a probability of asteroids being threat to our planet. Therefore, it is extremely important to track them. Sometimes, interaction with a planet's gravitational field knocks these asteroids off their trajectories and sends them towards a planet like Earth for potential impact.
When NASA's telescopes track a new Near-Earth Asteroid (NEA), astronomers measure the asteroid's observed positions in the sky and report them to the Minor Planet Center. The Center for Near-Earth Object Studies (CNEOS) then uses that data to determine the asteroid's most likely orbit around the Sun.
The asteroid which has given the designation of Asteroid 2023 QR- by NASA, is on its way towards Earth today, August 20. The asteroid was tracked by NASA's Defense Coordination Office (PDCO). It is responsible for monitoring the skies and keeping a watch on various Near-Earth Objects (NEOs). The size of this asteroid is just 16 feet wide. Its size is not big enough to become a potential threat for Earth. However, its closest approach to Earth can be a concern.
It is hurtling towards the planet at a blistering speed of 75165 kilometers per hour and will pass the planet at a distance of about 129,000 miles, which categorises it as
