An orbit of about 45000km with period of 1/20 Moon period would be sufficient; 1/20 of its circumference at its maximum distance converts to about 1.85 degree angular diameter from the Moon; Earth angular size is 1.84 degree when seen from the Moon. | |

It's a very elegant solution and the orbit wouldn't need to be all that terribly high; a polar orbit of altitude close to GEO (but polar) would easily suffice, with 1/27 moon period, moving in phase such that it's never eclipsed by Earth. | |
