Asteroids are dangerous space rocks and history has so many instances of it. Of the really notable ones is the one that collided with the planet nearly 65 million years ago, which is said to be the reason behind the extinction of dinosaurs. Though the collision was cataclysmic and caused the dinosaurs to cease to exist, our planet survived! Does this mean that Earth cannot be destroyed by an asteroid even though living things on it may go extinct? Absolutely not! A big asteroid can do even that. Due to the Earth's gravitational pull, the planet tends to attract celestial objects like asteroids and meteors towards it leading to surface impacts.
The responsibility of keeping a watch on these Near-Earth Objects (NEOs) falls to NASA who uses its various ground and space-based telescopes to monitor and flag these objects.
Now, NASA has revealed that another asteroid is on its way hurtling towards Earth today.
NASA has warned that Asteroid 2019 BZ4 is on its way towards Earth today, January 24, travelling at a staggering speed of 20171 kilometers per hour. It will make its closest approach to the planet at a distance of 6.3 million kilometers. According to NASA, Asteroid 2019 BZ4 is almost the size of a commercial aircraft with a width of nearly 62 feet!
According to the-sky.org, Asteroid 2019 BZ4 belongs to the Apollo group of asteroids which are a group of near-Earth asteroids named after the humongous 1862 Apollo asteroid, discovered by German astronomer Karl Reinmuth in the 1930s.The asteroid orbits the Sun in around 735 days. During this trip, its farthest point from the Sun is at 327 million kilometers and its nearest point is 150 million kilometers.
One asteroid that NASA is studying up close, called Bennu, has a 1/2700
