The lessons learned could limit, or even prevent, global devastation should the scenario play out for real in the future. So, to test their operational readiness, the international planetary defense community will sometimes use a real asteroid's close approach as a mock encounter with a 'new' potentially hazardous asteroid. Watching the skies for large asteroids that could pose a hazard to the Earth is a global endeavor.

Over 100 participants from 18 countries – including NASA scientists and the agency's NEOWISE mission – took part in the international exercise. Planetary Defense Exercise Uses Apophis as Hazardous Asteroid Stand-In At bottom left is an illustration of the path of Apophis’ close approach in 2029.Ĭredit: NASA/JPL-Caltech/University of Arizona The DART mission spacecraft will reach its target in September, 2022.Clockwise from top left are three of the observatories that participated in a 2021 planetary defense exercise: NASA’s Goldstone planetary radar, the Mount Lemmon telescope of the Catalina Sky Survey, and NASA’s NEOWISE mission. NASA's Double Asteroid Redirection Test (DART), which launched last year, will involve slamming a spacecraft into an asteroid far away from Earth to see whether humans could push a space rock out of the way in future if it seemed like it was going to strike our planet. Scientists are also preparing for a future event in which an asteroid impact on Earth would be imminent. Around 900 of these are more than one kilometer, or 3,280 feet, in size. Today, scientists track more than 28,000 near-Earth asteroids as they travel through the solar system. The agency's planetary defense officer Lindley Johnson called it a 'cosmic wake-up call.' About 1,600 people were injured, mostly due to broken glass, according to NASA.

Still, even relatively small asteroids can have serious consequences. 2022 ES3 certainly meets the distance requirement, but it falls short in terms of size. Specifically, asteroids that can't get any closer to Earth than around 4,650,000 miles or are smaller than about 500 feet in diameter aren't considered PHAs. In order for an asteroid to be classed as a potentially hazardous asteroid, or PHA, it must meet certain criteria regarding size and how close it could get to our planet. The asteroid is predicted to be somewhere between 33 and 72 feet in diameter-about as wide as the length of a bowling lane. Asteroid Isn't Considered HazardousĪstronomers don't consider 2022 ES3 to be potentially hazardous, probably due to its size. An Italian astronomy organization called the Virtual Telescope Project, which often tracks asteroids and other space objects through the sky, is due to host a livestream of what it calls 2022 ES3's 'very close, but safe, encounter with us' on its WebTV page starting at 18:30 UTC on March 13th. The event provides a great viewing opportunity. Instead, it will pass by at a distance of about 206,000 miles, which is about 87 percent of the distance between us and the moon. The space rock isn't expected to hit Earth. ET on Sunday, March 13, according to NASA's Center for Near Earth Object Studies (CNEOS). The asteroid, called 2022 ES3, will be traveling at 41,000 miles per hour when it comes between the moon and the Earth at around 2:18 p.m.

An asteroid is set to zoom past Earth at a relatively close distance this week, and the event can be viewed live.
