Equal and opposite reactions.

If the sun was perfectly still there wouldn't be a problem. But earth (mostly jupiter, due to mass&distance) pull on the sun too.

If the sun's gravity appears to be coming from where it was 8 minutes ago, that would be slightly in front of us, rather than directly opposite the center of mass.
Accelerating forwards would spin us out into deep space.
