I get 9.122*10^26 pies using Wiki’s value for Jupiter’s mass and a good calculator. Using my 55-year-old slide rule and a pencil to keep track of exponents, I get 9.1 * 10^26. The slide rule figure is close enough for government work. I would like to point out that 2.08kg seems a bit optimistic on the pie mass, though.
U2 reference?
