In the close approach that led to the first time it was found, not enough sightings could be made to find out it's orbit, and Adonis was lost until 1977 when it was found once again by Charles T. Kowal.
It comes within 30 Gm of the Earth six times in the 21st century, the nearest being 5.3 Gm in 2036.
