Uranus' pole points towards the earth/sun at this time.  In about 44 years ( I think it's orbital period is about 176 years) 
, it's pole will point tangent to it's orbit (i.e. it's pole, like ours, points towards some point in space reguardless of it's position in it's orbit). In 88 years Uranus' other pole will point towards the earth. 



As an extra, What is the Ulysses probe? Will it also go to Jupiter?
