NASA says this asteroid is rushing towards Earth will come terrifyingly close at 439000 km

There are several asteroids that make a close approach towards Earth and NASA terms them as Potentially Hazardous if they come within 8 million kilometers of Earth. Although it is not a planet-killer, NASA scientists have warned about a terrifying asteroid that will pass very close to Earth today. So, how close will this space rock pass by and how fast is it going? Check out what NASA has to say.

NASA has issued an alert against an asteroid named Asteroid 2022 WQ3. This terrifying asteroid is expected to come extremely close to Earth today, November 22. Terrifyingly, its close approach will bring it within just 439000 kilometers of Earth. That is nearly the distance of Moon from Earth. The figure may seem large, but in astronomical terms, it is quite tiny. The asteroid is already on its way towards Earth, travelling at a staggering speed of 52394 kilometers per hour. Fortunately, this 27-foot asteroid is quite small.

According to the-sky.org, the Asteroid 2022 WQ3 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.

An asteroid's orbit is computed by finding the elliptical path about the sun that best fits the available observations of the object using various space and ground-based telescopes such as NASA's NEOWISE telescope and its brand-new Sentry II algorithm. 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 time.
