titan, a moon of saturn, has a 16 day orbital period and an orbital radius of 1,222,000 km. what is the mass of saturn?(adsbygoogle = window.adsbygoogle || []).push({});

my attempt:

t = 2*pi*r^(3/2)/sqrt(g*m)

t = 16 days = 1,382,400 s

r = 1,222,000/2 km = 611,000,000 m

1,382,400 = 2*pi*611,000,000^(3/2)/sqrt(6.67e-11*m) => m = 7.065e25 kg

the answer should be 5.6e26 kg, what am i doing wrong?
