NASA spots dangerous 64-foot wide asteroid zooming towards Earth today
NASA warns that a huge 64-foot wide asteroid will be coming dangerously close to the Earth today, December 15. Is there a danger of an asteroid strike? Find out.
![Space is full of objects, out of which only a few have been discovered. Asteroids are some of these objects. If you are not aware about the dangerous objects called asteroids, here are some facts you should know. First, did you know that asteroids are sometimes called minor planets? Well, they are. 2022 XO](https://images.hindustantimes.com/tech/img/2022/08/04/960x540/asteroid-4145080_1920_1646293428986_1659609459191_1659609459191.jpg)
![Differences between an Asteroid, Comet, Meteoroid, Meteor and Meteorite: According to the information provided by NASA, Asteroid is a relatively small, inactive, rocky body orbiting the Sun. Comet is a relatively small, at times active, object whose ice can vaporize in sunlight forming an atmosphere (coma) of dust and gas and, sometimes, a tail of dust and/or gas. Meteoroid is a small particle from a comet or asteroid orbiting the Sun. Meteor is the light phenomena which results when a meteoroid enters the Earth's atmosphere and vaporizes, in short, a shooting star. While, Meteorite is a meteoroid that survives its passage through the Earth's atmosphere and lands upon the Earth's surface. 2022 XO](https://images.hindustantimes.com/tech/img/2021/11/26/960x540/ygy_1637905928669_1637905952424.jpg)
![Asteroid: Size, frequency and impact- More than 100 tons of dust and sand sized particles are bombarded towards Earth everyday, according to NASA. While, about once a year, an automobile-sized asteroid hits Earth's atmosphere, creates an impressive fireball, and burns up before reaching the surface. Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area. Only once every few million years, an object large enough to threaten Earth's civilization comes along. Impact craters on Earth, the moon and other planetary bodies are evidence of these occurrences. Space rocks smaller than about 25 meters (about 82 feet) will most likely burn up as they enter the Earth's atmosphere and cause little or no damage. By comparison, asteroids that populate the main asteroid belt between Mars and Jupiter, and pose no threat to Earth, can be as big as 940 kilometers (about 583 miles) across. 2022 XO](https://images.hindustantimes.com/tech/img/2022/03/10/960x540/Ryugu_Hayabusa2_1024_1646887609294_1646887704075.jpg)
![How is an Asteroid Orbit Calculated? An asteroid's orbit is computed by finding the elliptical path about the sun that best fits the available observations of the object. That is, the object's computed path about the sun is adjusted until the predictions of where the asteroid should have appeared in the sky at several observed times match the positions where the object was actually observed to be at those same times. 2022 XO](https://images.hindustantimes.com/tech/img/2021/12/10/960x540/asteroid_(pixabay)_1639115875543_1639115887157.jpg)
![What is NASA doing to find and learn more about potentially hazardous asteroids and comets? NASA has established a Planetary Defense Coordination Office (PDCO), managed in the Planetary Science Division at NASA Headquarters in Washington, D.C. The PDCO ensures the early detection of potentially hazardous objects (PHOs) - asteroids and comets whose orbits are predicted to bring them within 0.05 Astronomical Units of Earth (5 million miles or 8 million kilometers) and of a size large enough to reach Earth's surface - that is, greater than approximately 30 to 50 meters. NASA tracks and characterizes these objects and issues warnings about potential impacts, providing timely and accurate information. NASA also leads the coordination of U.S. Government planning for response to an actual impact threat. 2022 XO](https://images.hindustantimes.com/tech/img/2022/01/02/960x540/US-SPACE-ASTEROID-NASA-DART-0_1641136501797_1641136520237.jpg)

The peak of the Geminid meteor shower was yesterday, December 14, but you can still watch the bright meteors moving across the sky for a few more days. However, you may see a particularly bright object across the sky and it might not be a meteor shower but a hazardous asteroid speeding towards the Earth. NASA has spotted a 64-foot wide asteroid that will be making its closest approach to our planet today, December 15. The risk is that an asteroid even this size can flatten a large landmass. So, how likely is the chance of an asteroid strike? Read on to find out.
Dangerous asteroid headed for the Earth
NASA reports on the asteroid have given us significant information on what to expect. The asteroid is named 2022 XO and it was first spotted on December 01 of this year, as per Small-Body database. The Jet Propulsion Laboratory (JPL) website tells us that the asteroid is going to come as close as 3.2 million kilometers to the Earth. While this might seem like a huge distance to some, the Center for Near Earth Objects Studies (CNEOS) data might shock you. According to them, the asteroid is traveling at a mind-numbing speed of 30,888 kilometers per hour!
However, do not panic. NASA prediction states that the asteroid will likely make a safe passage across the planet. Yet, for precautionary reasons, the asteroid is being monitored by the Wide-field Infrared Survey Explorer (NEOWISE) telescope. This tech marvel is a space telescope that has been tasked with monitoring all nearby space rocks in the inner circle of the solar system.

NASA's New Horizons is an interplanetary space probe that was launched as a part of NASA's New Frontiers program. The spacecraft was launched in 2006 with the primary mission to perform a flyby study of the Pluto system in 2015, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs) in the decade to follow, which became a mission to 486958 Arrokoth. It is the fifth space probe to achieve the escape velocity needed to leave the Solar System.
