A planet with a rotational axis in the plane of the solar ecliptic is
possible.  To get one side always facing the sun would require the sun to be
always along the rotational axis, with a precession matching the length of
the planet's year.  Thus it would appear to always be either due north or
due south of any observer.  It would not revolve in circles with size
growing larger away from the poles.  Rather is would remain in a stationary
position, as Polaris appears from Earth.  However, it would appear to spin
in place.
