What would happen to the earth's rotation, orbit, etc. if the planet were half as large, diameter-wise, as it is now?

My daughter wants to know what would happen to the planetary motion of the earth if it were suddenly to shrink down to half its current size (further questioning reveals she is thinking about it being roughly half as large in terms of diameter). Would its axial rotation speed up? How would its solar orbit be affected? Would it heat up?
I'm a SOCIAL scientist, dammit.
