Name the most giant planet in the solar system. 

It is located sixth from the Sun. It belongs to the outer planets because of the makeup. The mass of the biggest planet in the solar system is double that of all the other planets put together. It is large, but it also has 79 satellites. According to a recent research, it is ranked second among the planets with the most moons.

1. Given that it has the largest mass of any planet, Jupiter is the largest planet in our solar system.
2. Jupiter has a mass of $1.89\times {10}^{27} \mathrm{kg}$, and the volume is $1.43\times {10}^{15}{\mathrm{Km}}^3$
3. Amount of surface is $6.14\times {10}^{10}{\mathrm{Km}}^2$, and the average circumference$4.39\times {10}^5\mathrm{Km}$.
4. Jupiter's diameter is over 11 times that of the Earth.
5. The diameter of Jupiter is$139,820 \mathrm{km}$
6. As a result, Jupiter is the largest planet in our solar system.
In case of option A.
1. The diameter of Neptune is $49244 \mathrm{km}$.
2. That's less than Jupiter's.
3. As a result, option A is inaccurate.
In case of option D.
1. The diameter of Earth is $12742 \mathrm{km}$.
2. That's less than Jupiter's.
3. As a result, option D is inaccurate.

In case of option B.

1. The diameter of Saturn is $116460 km$.

2. That's less than Jupiter's.

3. As a result, option B is inaccurate.

Hence, the correct answer is option C.
