To be considered a success, mission planners determined that the orbit of Dimorphos would have to speed up by at least 73 seconds. The mission-which was a first test of the kind of asteroid deflection defense that could be used to protect the Earth from an incoming space rock-worked spectacularly. Rather, all of it is cause for celebration of the success of NASA’s Double Asteroid Redirection Test ( DART), which last September successfully crashed a small spacecraft into the asteroid moonlet Dimorphos, to see how much it could change the speed of its orbit around its parent asteroid Didymos. The asteroid will make nine more potentially close passes from Feb. A small asteroid hit Earth’s atmosphere over the Norwegian Sea before disintegrating on March 11, 2022. 14, 2046 will not be the only time 2023 DW swings by our way. That’s 18 times farther than the moon is from Earth.īut 2023 DW’s distance could change, as NASA itself admits, as further observations of the space rock are conducted and its trajectory is more finely calculated. So where does 2023 DW rank? For now, NASA puts it at a one, indicating “a routine discovery in which a pass near the Earth is predicted that poses no unusual level of danger.” For now, that pass near the Earth will be no closer than 7.5 million km (4.65 million mi.), according to NASA’s Eyes on Asteroids website. NASA calculates the risk a near-Earth object poses of colliding with Earth on something known as the Torino scale, a zero to 10 ranking of the likelihood of impact, with zero representing no danger or, a risk “so low as to be effectively zero.” Five on the scale indicates “A close encounter posing a serious, but still uncertain risk, of regional devastation.” Ten-which the dinosaurs could tell you about if they weren’t all dead-indicates that “a collision is certain, capable of causing global climatic catastrophe that may threaten the future of civilization as we know it.” 9), according to NASAs Asteroid Watch database. While NASA recently proved it can successfully alter the.
3 of the next 5 asteroids to fly near Earth are the approximate size of commercial airplanes, with the. The five asteroids, the smallest of which are bus-size, are skimming across Earths orbit between Friday (Sept. No asteroids are currently on a direct impact course with Earth, but more than 27,000 near-Earth asteroids exist in all shapes and sizes. 15, 2013, a projectile roughly half the size of 2023 DW exploded in the skies over Chelyabinsk, Russia, injuring 1,500 people and damaging more than 7,000 buildings. NASA tracks 5 potentially hazardous asteroids that will fly by Earth within days. The bad news is that a swimming pool sized piece of space rubble can still do a lot of damage. It’s nowhere near the 12 km (7.5 mi.) wide asteroid-more than half the length of Manhattan-that wiped out the dinosaurs 65 million years ago.

reveals that it completes a full orbit around the Sun in approximately 1370 days. This asteroid, classified under the Apollo group, was discovered just recently (on May 12, 2023). For starters, there’s the size of 2023 DW to consider-which is not that big, but not that small either. NASA data revealed that Asteroid 2023 MD2 is set to make a close approach to Earth on July 11.
