But you CAN determine the size of the planets: in diameter, overall mass, and in density.
Uranus and Neptune are two outer planets that are similar in size. Both planets are known as ice giants and are similar in diameter and mass.
No, it is not.Saturn is the second largest of the planets, but nowhere near the diameter or mass of the sun.In fact, the mass of all the planets together is less than 1/500th of the sun's mass.
Neptune is almost the same size as Uranus. Both planets are similar in diameter, mass, and composition.
The planets are normally classified in size by their equatorial diameter.
Once you know their distances, you can determine basic properties of the planets such as mass, size, you can determine its linear diameter.
The two planets that are closest in size to Earth are it's neighbours: Venus and Mars. Of the two, Venus is nearly the same size, with a diameter of 12,104km (compared to Earth's diameter of 12,756km). Mars is smaller - almost half the size of Earth - with a diameter of 6792km.
99.8 percent of the total mass of our solar system is the Sun, and most of the rest is Jupiter. If there were 500 planets the size of Jupiter, they would STILL all fit inside the Sun.
The largest terrestrial planet among the eight in our solar system is Earth. It has a diameter of about 12,742 kilometers (7,918 miles) and is the only planet known to support life. While Venus is similar in size, Earth has a greater volume and mass, making it the largest of the terrestrial group.
Jupiter is the largest planet in our solar system, with a diameter about 11 times that of Earth. It is also the most massive planet, containing more than twice the mass of all the other planets combined.
Venus has almost the same mass and diameter as the earth.
