Detailed explanation-1: -Neptune’s equatorial diameter measured at the one-bar pressure level (the pressure of Earth’s atmosphere at sea level) is 49, 528 km (30, 775 miles), which is only about 3 percent shy of the diameter of Uranus.

Detailed explanation-2: -solar system in terms of the relative planetary sizes. Problem 1-Saturn is 10 times bigger than Venus, and Venus is 1/4 the size of Neptune.

Detailed explanation-3: -Saturn is the second largest planet in the solar system with a diameter of 120, 000 km. It orbits the Sun every 30 years at a distance of about ten times that of the Earth’s. Saturn is the least dense of all the planets, its mean density being only 0.7 times that of water.

Detailed explanation-4: -The diameter of Neptune is 49, 500 km. Need some comparison? That’s approximately 3.9 times the diameter of Earth. In other words, you could put almost 4 Earths side to side to match the diameter of Neptune.
