The 99942 Apophis is a notorious asteroid which has worried scientists for a long time. First discovered in 2004, the asteroid gave the impression for the longest time that it will surely hit Earth during its closest approach on April 13, 2029. And there are reasons for this worry. Shockingly, the massive 370 meters or 1,210-feet wide asteroid is expected to come as close as 20,000 miles to Earth. For reference, this is closer than some of the geostationary satellites in the sky around the Earth. With an asteroid passing at such close distance, there is always a chance that it could get attracted to the Earth by its gravity and crash. And if an asteroid of this size strikes us, it would without a doubt cause a massive disaster. So, will it hit us? Read on to find out.
After its discovery in 2004, astronomers grew very concerned about a real possibility of it striking the Earth. In fact, the possibility kept it at level 1 on the Torino impact hazard scale for a couple of years. The Torino scale is a method for categorizing the impact hazard associated with near-Earth objects (NEOs) such as asteroids and comets. Level 1 indicates that there is a possibility that the asteroid could come very close to the Earth. However, additional observations of the asteroid have now determined that there is no real possibility of an asteroid strike.
“When I started working with asteroids after college, Apophis was the poster child for hazardous asteroids. With the support of recent optical observations and additional radar observations, the uncertainty in Apophis’ orbit has collapsed from hundreds of kilometers to just a handful of kilometers when projected to 2029. This greatly improved knowledge of its position in 2029 provides more
