The asteroid was later lost and could not be found again until 1977. Calculations have shown that in 1926 Adonis approached the earth to within 2.5 million kilometers.

Adonis moves on an eccentric orbit between 0.4406 AU ( perihelion ) and 3.3069 AU ( aphelion ) around the sun in 2.56 years . The eccentricity of the orbit is 0.7649, with the orbit inclined at 1.348 ° to the ecliptic .

The size of Adonis is estimated at 0.5 to 1.2 km.
