Triple Terror! 3 giant asteroids coming towards Earth today; NASA reveals speed and more

    NASA has warned about three potentially hazardous asteroids, one of which measures a massive 140-foot in size, that are coming towards Earth. Know what NASA says.

    Are near-Earth objects DANGEROUS? Know what NASA says about scary comets, asteroids
    Asteroid and Earth
    1/5 Earth has objects near it, which sometimes get attracted towards the planet because of its gravitational pull. Of course, not every near-Earth object manages to reach the surface of the planet. The object needs to be large enough to survive its fiery journey through the atmosphere of the Earth. (Pixabay)

    2/5 What is a near-Earth object? Asteroids or comets that can pass within 30 million miles or 50 million kilometers of Earth's orbit are known as near-Earth objects or NEO. According to NASA, "A near-Earth object (NEO) is an asteroid or comet whose orbit brings it within a zone approximately 121 million miles (195 million kilometers) from the Sun, meaning that it can pass within about 30 million miles (50 million kilometers) of Earth’s orbit."

    3/5 NASA further informed that the vast majority of NEOs that enter Earth’s atmosphere disintegrate before reaching the surface (and more than 100 tons of dust particles disintegrate in Earth’s atmosphere daily). Those NEOs that are larger than around 98 to 164 feet (30 to 50 meters) in size could cause widespread damage in and around their impact sites. Apart from NEOs, there is another category that NASA uses. These are the potentially hazardous objects (PHO). These are near-Earth objects whose orbit brings them within 4.7 million miles (7.5 million km) of Earth’s orbit, or is greater than 500 feet (140 meters) in size. (Pixabay)
    4/5 The highest risk of impact for a known asteroid is a 1 in 714 chance of impact by an asteroid designated 2009 FD in 2185. This means that the possibility that it could impact then is less than 0.2 percent. NASA said, "One asteroid that NASA is studying up close, called Bennu, has a 1/2700 chance of impacting Earth between 2175 and 2195. The OSIRIS-REx spacecraft will complete a 2-year investigation of Bennu before plucking a sample of asteroid material off its surface and delivering it back to Earth." (Pixabay)
    5/5 How can we prevent an asteroid from hitting Earth? Currently, an asteroid impact is the only natural disaster that NASA might be able to prevent. There are a few methods that NASA is studying to deflect an asteroid on a course to impact Earth. One of these techniques is called a gravity tractor—it involves a spacecraft that would rendezvous with an asteroid (but not land on its surface) and maintain its relative, optimal position to use the mutual gravity attraction between the satellite and the asteroid to slowly alter the course of the asteroid.

    Some asteroids surprise astronomers and come out of nowhere to hit Earth as happened just a few days ago. This asteroid was discovered just a few hours before impact. Thankfully, the undetected asteroid was too small in size to cause any serious impact and it ended up raining a few meteorites on Canada as most of it burned up in the atmosphere. However, that might not be the case every time! You must have heard tales about the infamous Chicxulub asteroid that caused massive destruction on Earth around 66 million years ago. This is the asteroid that ended the era of the dinosaurs. And that is why the fear of asteroids is constantly present even today!

    Now, NASA has spotted three giant monster rocks approaching Earth today, which pose a great risk to our planet. The worrying part is that these asteroids are marked as potentially hazardous because of the uncomfortably close distance that they are expected to come to Earth. NASA explains that any asteroid that comes within 4.6 million miles or 7.5 million kilometers of Earth, or if it measures larger than about 150 meters is said to be a potentially hazardous object. Know all about these asteroids.

    Upcoming asteroids today

    One of these three upcoming asteroids today measures 88-foot and is named asteroid 2022 VQ. NASA's JPL informed that it will come dangerously close, around 1.81 million miles to Earth. Moreover, it will be hurtling toward Earth at a speed of 29529 km per hour.

    There is another asteroid named 2022 WO2 which is zooming towards Earth at a blistering speed of 36162 km per hour, CNEOS data mentioned. It is a 71-foot wide asteroid that will come as close as 3.63 million miles to the Earth.

    Asteroid 2022 WP5, which measures a whopping 140-foot in size, is ready to make the closest approach at 3.79 million miles at a speed of 51875 km per hour.

    However, to detect further danger from these asteroids, NASA is constantly keeping an active eye on them. NASA uses data from observatories and telescopes such as Pan- STARRS, the Catalina Sky Survey, and the NEOWISE telescope to analyse the danger these asteroids pose to Earth.
