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. --- Marc Majka

Such motion is impossible unless the two rates of rotation are equal. Such motion would not conserve angular momentum. -Dave Godman
