Three giant asteroids, namely 2005 RX3, 2022 QB37 and 2022 SB, are moving towards Earth today. While one is a monster at 390 feet, which is the size of a building, another is 180 feet, which is the size of an airplane. Are they dangerous? Find out here.
Sunday September 18 is going to be pretty dangerous for planet Earth! Do you want to know why? Three giant asteroids, namely 2005 RX3, 2022 QB37 and 2022 SB, are on their way to our planet today. Asteroid 2005 RX3 is the largest of them all, measuring 390 FT (building size). The closest approach to Earth will be 2,950,000 miles. The 2022 QB37 is the size of an airplane (180 FT) and will make a closest approach to Earth of 4,080,000 miles. Asteroid 2002 SB is the smallest of them all and is the size of a bus (36 FT). How close will this asteroid get to Earth? Scary, the closest approach to the planet will be just 7.24,000 miles. That’s way too close for comfort. Compare it to the distance from the moon to the earth, which is 238 855 miles. Yes, the asteroid will be closer to Earth than the moon.
How dangerous are these asteroids to our planet?
According to information from NASA’s Jet Propulsion Laboratory, all three asteroids will whiz past Earth on Sunday and therefore cause no damage or threat to the planet. according to JPLan object larger than about 150 meters and capable of approaching the earth as far as 7.5 million kilometers or 19.5 times the distance from the moon is called a potentially dangerous object.
Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to approach threateningly close to Earth. According to the Center for Near Earth Object Studies, asteroids that cannot get closer to Earth (i.e. MOID) are 0.05 au (about 7,480,000 km or 4,650,000 miles) or smaller than about 150 m (500 ft) in diameter (i.e. H = 22.0 with assumed albedo of 13%) are not considered PHAs.
It can also be noted that the potential to get close to Earth does not mean that a PHA will affect the Earth. It just means that there is a possibility for such a threat. By monitoring these PHAs and updating their orbits as new observations become available, the research organization can closely predict the statistics and thus their threat to the Earth impact.
The technology behind the science: how NASA studies and tracks asteroids near and far
Surveys conducted by NASA-supported ground-based telescopes — including Pans-STARRS1 in Maui, Hawaii, as well as the Catalina Sky Survey near Tucson, Arizona — have identified thousands of near-Earth objects. And a space-based telescope called NEOWISE has identified hundreds of others as it scanned the sky for near-infrared wavelengths of light from its polar orbit around Earth. Many ground-based telescopes conduct follow-up observations to further aid orbit calculations and study the physical properties of the objects. These gadgets contain the best technologies of the time they were built, from chips to software.
