NASA WARNING! Asteroid 2022 QR, clocked at a fiery 31000kmph; it will just miss Earth TODAY

NASA has issued a warning that an asteroid named Asteroid 2022 QR will just about miss Earth today as it flies by. Here's what we know about it.

Asteroid fun facts in pics: NASA reveals all you need to know
1/5 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.

2/5 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. (NASA)
3/5 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. (NASA)
4/5 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.

5/5 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. (AFP)

Asteroid flybys have been a frequent occurrence these past few weeks with over 35 asteroids just missing Earth by a close distance. People who are interested in astronomy can take out their telescopes to watch these celestial bodies fly past Earth. However, these asteroids can potentially cause destruction if they impact with Earth. NASA has now issued another asteroid warning. A 42-foot asteroid named Asteroid 2022 QR will make its closest approach to Earth today, August 24.

Asteroid 2022 QR to get very close to Earth

According to NASA, Asteroid 2022 QR will fly closely past Earth today. The asteroid is expected to make its closest approach at 17:07 UTC time. Asteroid 2022 QR is nearly 42 feet, which is as big as a bus, travelling at nearly 31,000 kilometers per hour. NASA's JPL has confirmed that this asteroid will not crash on Earth. It is expected to fly past Earth at a distance of merely 1.3 million kilometers, which is a distance equivalent to 3.5507 Lunar Distance. That might seem a lot but NASA's Planetary Defense Coordination Office has still classified it as a “Potentially Hazardous Object” due to the close proximity by which it will fly past Earth.

How does NASA maintain asteroid watch?

NASA's Planetary Defense Coordination Office is responsible for monitoring the skies and keeping a watch on various Near-Earth Objects (NEOs). If any celestial object is at risk of Earth impact, it red flags and issues the alert. Asteroids which come closer than 28 million miles from Earth's orbit are classified as potentially hazardous asteroids, according to NASA.

With the help of advanced telescopes, more than 750,000 asteroids have been discovered to date, of which more than 27,000 are near-Earth asteroids.
