The shock wave blew out windows, knocked down parts of buildings in six Russian cities, and injured 1,500 people (mostly from flying glass). Even though the roving space rock will miss our planet, NASA still classifies it as a potentially hazardous asteroid, given its size and relative proximity to Earth. That asteroid-which was around 65 feet long-exploded after entering Earth's atmosphere, carrying 20 to 30 times the energy of the Hiroshima atomic bomb, according to Earth Sky. Even though the roving space rock will miss our planet, NASA still classifies it as a potentially hazardous asteroid, given its size and relative proximity to Earth.Any object larger than 460 feet. Per Earth Sky, 2023 DZ2 is three times larger than an asteroid that entered over Chelyabinsk, Russia in February 2013. Per Earth Sky, it should appear as a "slow-moving star" passing in front of the fixed stars in the sky above the southeastern horizon, east of the constellations Orion, Canis Major and Canis Minor. The Virtual Telescope Project is also hosting a live stream of the asteroid at 6:30 p.m. The ultra-valuable asteroidwhich appears to be made largely of iron, nickel, gold and other rare metals orbits the Sun between Mars and Jupiter. Stargazers wanting to observe the visitor will have the best opportunity to see the 2023 DZ2 on Friday evening using a six-inch or larger telescopes from the Northern Hemisphere. Astronomers with the International Asteroid Warning Network are using the close approach to learn as much as possible about the asteroid, which is good practice for if there's a potential asteroid threat in the future.Īsteroid 2023 DZ2 is expected to pass by Earth at less than half the distance of the moon on Saturday. ![]() ![]() "While close approaches are a regular occurrence, one by an asteroid of this size (140-310 ft) happens only about once per decade, providing a unique opportunity for science," tweeted NASA Asteroid Watch on Tuesday.
