When you fold a piece of paper, it doubles in width. If you double it 51 times: 2^{51} ≈ 2.25 x 10^{15}.

A sheet of paper is approximately 0.1 mm.

0.1 mm x 2.25 x 10^{15}

= 2.25 x 10^{14} mm (multiply by 0.1)

= 2.25 x 10^{13} cm (divide by 10)

= 2.25 x 10^{11} m (divide by 100)

= 2.25 x 10^{8} km (divide by 1000)

= 225, 000, 000 km

The distance from the earth to the sum is approximately 149, 600, 000 km

It's pretty much impossible to fold a piece of paper more than about eight times, so the question is pointless.
