Mercury and Venus are always seen in the dusk or dawn sky since they orbit the sun interior to the earth, hence we are always looking in the direction of the sun when we observe them. Mercury is by far the most elusive of the twilight pair since it is closest to the sun and id usually lost in the suns glare. Go out the next few nights and see Venus and Mercury together. Mercury is so elusive that even Copernicus was said to never have observed it himself.
