Asteroids often pass Earth at close distances, posing a threat to the planet with their terrifying approaches. Most of them might seem like they're just floating rocks in space, but did you know asteroids have differing compositions? These space rocks can be classified into 3 types based on their structural composition. The most commonly found asteroids are S-type, which are made up of carbon-rich substances. On the other hand, S-type asteroids are made up mainly of silicate minerals and are less common. M-type asteroids are the least prevalent and they are primarily composed of metal.
In a separate development, NASA has issued details about an asteroid expected to make its closest approach to Earth today.
With the help of its advanced ground and space-based telescopes, NASA has tracked an asteroid whose orbit will bring it very close to Earth today. As per the Center for Near-Earth Object Studies (CNEOS), an asteroid, given the designation of Asteroid 2023 QC8, is on its way toward Earth and could make its closest approach to the planet today, October 5.
This near-Earth space rock is expected to make its closest approach to the planet at a distance of 6 million kilometers and at a speed of 22741 kilometers per hour which is much faster than Intercontinental Ballistic Missiles (ICBMs)!
According to NASA, this space rock belongs to the Amor group of Near-Earth Asteroids which are Earth-approaching near-Earth asteroids with orbits exterior to Earth but interior to Mars', named after asteroid 1221 Amor, which was discovered by Belgian astronomer E. Delporte in 1932.
In terms of size, Asteroid 2023 QC8 is nearly 130 feet wide, which makes it almost as big as an aircraft! Despite being more than two times bigger than the
