A Visit from Near-Earth Asteroid 2011 ES4 – Is It Dangerous?
On September 1, 2020 (plus or minus a week), Earth will be visited by a celestial wanderer named Asteroid 2011 ES4. This asteroid is one of a class called Apollo asteroids. The name Apollo has nothing to do with the NASA Lunar Landing Program, but everything to do with Near-Earth Asteroids with orbits which cross the Earth's orbit similar to an asteroid named 1862 Apollo.
