I just thought I'd add something I found recently.
A cardioid is a shape that is very similar to this, and I thought I'd try and approximate it. It turns out its not a cardioid, but its very close, and can be approximated with the parametric equations:
\( x(t) = a \cos(t) (1+\cos(ct)) \)
\( y(t) = a \sin(t) (1+\cos(ct)) \)
where a = 1.36 and c = 1.17
