(1862) Apollo is the namesake of a group of asteroids , the Apollo asteroids . These are heavenly bodies whose orbits can cross the earth's orbit .
The asteroid was discovered by Karl Wilhelm Reinmuth in 1932 and named after Apollon , a god of Greek mythology .
Apollo moves at a mean distance of 1.471 astronomical units in around 650 days on a strongly eccentric orbit around the sun. In doing so, it can approach the earth up to 5 million km.
Using radar observations with the Arecibo observatory , it was possible to prove in 2005 that Apollo is accompanied by a small moon . The companion has a diameter of around 75 meters and runs around the asteroid at a distance of around 3 km.
