Earth actually has a few better quasi-satelites. (164207) 2004 GU9, (277810) 2006 FV35, 2014 OL339 [1][2][3] these are very small bodies typically ~100-300 meters by 50-200 meters.
That also orbit in 1:1 resonance with the earth, their orbits are less eccentric (not sun diving), meaning they can be reached with relatively very low D-V requirements on the order of 11-13km/s, also incredibly weak gravity of their own. (This doesn't count trojan bodies that orbit Earth/Sun L4/L5 points, which have been observed [5]).
Most quasi-satellites are typically temporary, Neptune currently has a large one ~250km long, Venus even has one that'll only orbit for another 500 years [4].

Orbital mechanics and near earth objects are really cool!
