One of the satellites of Jupiter has an orbital period of \(1.769\) days and the radius of the orbit is \(4.22 \times 10^{8}\) m. The ratio of the mass of Jupiter and the mass of the sun nearly is:
1. \(1000:1\)
2. \(1:1000\)
3. \(1:1\)
4. \(2000:3\)
If the mean orbital radius of the earth around the sun is . Then the mass of the sun is approximately:
1. 3 × 1034 kg
2. 2 × 1030 kg
3. 1.5 × 1028 kg
4. 1.0 × 1035 kg
