I thought of using vardef but that is kind of verbose because I gave to repeat
"rotated angle" three times.

\startMPpage
  vardef orbital(expr angle) =
    save p ;
    path p ;
    p := origin .. (2,1) .. (3,0) .. (2,-1) .. (-2,1) .. (-3,0) .. (-2,-1) .. cycle ;
    image (
      draw p scaled 6 rotated angle;
      label("\strut$+$",(+10,0) rotated angle);
      label("\strut$-$",(-10,0) rotated angle);
    )
  enddef ;

  picture px, py ;
  px := orbital ( 0) ;
  py := orbital (90) ;

  draw px ;
  draw py ;
\stopMPpage
