Amateur astronomers have the chance to spot a huge asteroid flying past Earth over the next few days — all from their own backyards.
Asteroid Florence is quite big as far as asteroids go: at 2.7 miles across, it's the biggest to pass earth since NASA started keeping records, according to the space agency.
"While many known asteroids have passed by closer to Earth than Florence will on September 1, all of those were estimated to be smaller," Paul Chodas, manager of NASA’s Center for Near-Earth Object Studies, said in a statement.
It will cruise by at a safe distance of 4.4 million miles or about 18 times the distance between the earth and the moon, NASA said. This is the closest that Florence has been since 1890 on its travels through the solar system, according to the agency, and will not come this close again until after the year 2500.
