NASA discovered an asteroid that in September 2020 flies past Earth at a closer distance than the Moon. According to researchers, the diameter of the asteroid ES4 is about 22-49 meters. It will fly past Earth at a speed of 18,253 miles per hour, which roughly corresponds to the standard speed of an asteroid.
NASA noted that the proximity of a celestial body to Earth is “potentially dangerous.” However, scientists did not put it on the list of dangerous because of the small diameter of the asteroid.
According to the database, the asteroid will pass the Earth on September 1 at 10:49 a.m. EST. ES4 will fly at a distance of 0,00048 astronomical units, or about 44,618 miles. The distance to the Earth is much closer than to the Moon, which is at a distance of about 238,855 miles. Scientists have not seen the asteroid since March 2011, so they hope to get an idea of its journey in September 2020.
In total, NASA listed 12 asteroids that should fly past Earth by the end of July. All of them fly an unsafe distance from the planet.
