Three massive asteroids 2005 RX3, 2022 QB37 and 2022 SB are heading toward Earth today. While one is a monster of 390 feet, which is the size of a building, the other is 180 feet, which is the size of an airplane. Are they dangerous? Discover it here.
Sunday, September 18 will be very dangerous for planet Earth! Want to know why? Three massive asteroids, 2005 RX3, 2022 QB37 and 2022 SB, are heading toward our planet today. Asteroid 2005 RX3 is the largest of all and measures 390 feet (the size of a building). Its closest approach to Earth will be 2,950,000 miles. 2022 QB37 is the size of an airplane (180 feet) and will come close to Earth 4,080,000 miles. Asteroid 2002 SB is the smallest of all and is about the size of a bus (36 feet). How close is this asteroid to Earth? Temporarily, its closest approach to the planet will be only 7,24,000 miles. This is very close to convenience. Just compare it to the moon’s distance from 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 provided by NASA’s Jet Propulsion Laboratory, all three asteroids will pass over Earth on Sunday, and therefore will not cause any harm or threat to the planet. According to JPLAn object over 150 meters in size that can approach Earth within 7.5 million km or 19.5 times the distance to the Moon is called a potentially dangerous name.
Potentially Hazardous Asteroids (PHAs) are currently defined based on criteria that measure an asteroid’s ability to approach dangerously close to Earth. According to the Center for Near-Earth Object Studies, asteroids that cannot come close to Earth (i.e. MOID) more than 0.05 au (about 7,480,000 km or 4,650,000 miles) or smaller than about 150 meters (500 feet) at Diameter (ie H = 22.0 with assumed albedo of 13%) PHAs are not considered.
Also, it can be seen that the possibility of approaching the Earth does not mean that the PHA will affect the Earth. It just means that there is potential for such a threat. By observing this PHA and updating its orbits as new observations become available, the research organization can predict close approach statistics and thus threaten its impact on Earth.
The technology behind the science: How NASA studies and tracks asteroids near and far
Surveys 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 NEOs. A space telescope called NEOWISE has identified hundreds of others while scanning the sky at near-infrared wavelengths from its polar orbit around the Earth. Many ground-based telescopes make follow-up observations to aid in orbit calculations and study the physical properties of objects. These tools contain the best technology used back in the day when they were made, from chips to software.
