   Apophis is about 1,100 feet (340 meters) in width. It’s expected to safely pass close to Earth – within 19,794 miles (31,860 kilometers) from our planet’s surface – on April 13, 2029. This will be the closest approach to Earth by an asteroid of this size that scientists have known about in advance.

   26 mar 2021 · This animation depicts the orbital trajectory of asteroid 99942 Apophis as it zooms safely past Earth on April 13, 2029. Earth’s gravity will slightly deflect the trajectory as the 1,100-foot-wide (340-meter-wide) near-Earth object comes within 20,000 miles (32,000 kilometers) of our planet’s surface. The motion has been speeded up 2,000 times.

   In fact, collisions of asteroids with the early Earth may have been the key to delivering water to our planet (e.g., Daly & Schultz, 2018), enabling life as we know it. Now, billions of years later, the influx of small bodies in the inner Solar System is much lower.

   3 lip 2024 · Because close approaches by asteroids the size of 2024 MK are relatively rare, JPL’s planetary radar team gathered as much information about the near-Earth object as possible. This mosaic shows the spinning asteroid in one-minute increments about 16 hours after its closest approach with Earth.
