Problem

Titan’s orbital data are again:

T_1 = 15.9\,\text{days}

a_1 = 1.22\times10^{6}\,\text{km}

. Enceladus, another moon of Saturn, has an orbital period of

T_2 = 1.37\,\text{days}

. Estimate the orbital radius

a_2

of Enceladus. a)

6.30\times10^{9}\,\text{m}

4.90\times10^{8}\,\text{m}

2.35\times10^{8}\,\text{m}

1.05\times10^{8}\,\text{m}
