Are near-Earth objects DANGEROUS? Know what NASA says about scary comets, asteroids

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.

Earth may face a bit of danger from this upcoming asteroid hurtling towards Earth at terrifying speed! A huge "potentially hazardous" asteroid zoomed by yesterday after it made its closest approach towards Earth. This was a 62-foot-sized Asteroid 2022 UD71. But the fear of these horrific space rocks is not over! The National Aeronautics and Space Administration (NASA) has issued a warning that another massive airplane-sized space rock, asteroid 2022 WP5, will make its closest approach to Earth today. NASA has flagged it as a "potentially hazardous object".

The reason is its close proximity! According to NASA's Jet Propulsion Laboratory (JPL), the upcoming asteroid is 140-foot in size and is expected to come as close as 3.79 million miles toward the Earth. NASA's Center for Near Earth Object Studies (CNEOS) confirmed that the asteroid will come with a blazing speed of 51875 km per hour. NASA keeps constant track of these monstrous space rocks which pose any danger to the Earth.

NASA says any asteroid that approaches to within 4.6 million miles of the Earth and having a size larger than about 150 meters is termed a potentially hazardous object. This is the reason that Asteroid 2022 WP5 is flagged as a potentially hazardous object. NASA will keep an eye on this upcoming asteroid, in case it poses any threat to Earth.

Do you know?

You will usually find asteroids with a nomenclature such as 2022 WP5. However, this is a provisional designated name for an asteroid which mentions the year of its discovery followed by two letters which denote the order of its discovery during that year. For example, if an asteroid is discovered between 1 and 15 January, then it will be designated as AA, AB, AC, and so on. While, final discoveries of the year between 16 and 31 December will get YA, YB, YC, and so on. However, for some reason, it doesn't include the letter J.

NASA takes the help of some of the best technologies to know about these asteroids such as, with the use of optical and radio telescopes, NASA determines the size, shape, rotation, and physical composition of asteroids. For detailed characterization data of the asteroids, NASA uses radio telescopes at Deep Space Network and the National Science Foundation's Arecibo Observatory in Puerto Rico.
