Calculate C in the units of d²/AU³ for each orbital body listed in this table. Use the formula T² = Ca³ and the proper number of significant digits in your value for C. The first one has been done for you. and the proper number of significant digits in your value for C. The first one has been done for you.

 

Body	Period T (d)	Semi-major axis a (AU)	T2 (= d2)	a3 (= AU3)	C (= d2/AU3)
Mercury	88.0	0.387	(88.0)2 = 7.74 103	(0.387)3 = 5.80 10-2	1.34 105
Ceres	1.68 103	2.77
Uranus	3.08 104	19.2
