== Classification and orbit ==

The moderately bright [[V-type asteroid]] is also an [[Apollo asteroid]], as well as a [[Venus-crosser asteroid|Venus]] and [[Mars-crosser asteroid|Mars-crosser]]. The asteroid orbits the Sun at a distance of 0.6–2.9&nbsp;[[Astronomical unit|AU]] once every 2 years and 4 months (864 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.65 and an [[orbital inclination|inclination]] of 40[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata"/>

''Midas'' has a low [[minimum orbit intersection distance]] with Earth of {{convert|0.0036|AU|km mi|abbr=on|lk=off}}, which corresponds to 1.5 lunar distance (Earth–Moon distance). However, it does not pose an impact risk for the foreseeable future. On 19 March 1947 it passed {{convert|0.0298|AU|km mi|abbr=on|lk=on}} from Earth.<ref name=jpl-close/> The last notable close approach was on 21 March 2018 passing {{convert|0.08957|AU|km mi|abbr=on|lk=off}} from Earth<ref name=jpl-close/> and shining at an [[apparent magnitude]] of +12.4.<ref name="NEODyS2018"/> The next notable close approach will be on 14 September 2032 passing slightly closer at {{convert|0.08635|AU|km mi|abbr=on|lk=off}} from Earth.<ref name=jpl-close/> As no [[precoveries]] are known, the asteroid's [[observation arc]] begins with its discovery observation at Palomar in 1973.<ref name="MPC-Midas" />

With a semi-major axis of 1.78 AU, when 1 AU from the Sun (and passing Earth's orbit) the asteroid is moving at 35.7&nbsp;km/s with respect to the Sun.{{efn|name=speed}} For comparison [[Orbital speed#Planets|Earth orbits the Sun at 30 km/s.]]
