As it happens, this problem is very difficult to solve analytically (i.e. by integrating the equations of motion) but it is pretty easy to do numerically, to a fair approximation. Assuming I have not made any arithmetic mistakes, the graph below shows the distance from the Sun in metres as a function of time in seconds. Looks like you hit in about 88.8 days or so. Plenty of time to reconsider. :-)
