Like Pluto, the other trans-Neptunian dwarfs are likely composed of frozen gases and silicates, and few heavy elements. Mass estimates for such faraway objects use a number of techniques having varying degrees of accuracy. Ceres, which orbits in the asteroid belt between Mars and Jupiter, is thought to have a rocky core, a silicate mantle, and possibly liquid water beneath its frozen surface. (The unmanned NASA probe 'Dawn' will study Ceres and other asteroids when it explores the belt, beginning in 2012.)
The four smallest planets in our solar system are Mercury, Venus, Earth, and Mars. They are primarily composed of rock and metal, with varying amounts of silicate minerals, iron, nickel, and other elements. Each of these planets has a distinct composition and geology that contributes to their unique characteristics.

Mercury is the smallest planet in our solar system.
Are the first four planets the rocky planets?
Yes, the first four planets in our solar system are rocky planets. They are Mercury, Venus, Earth, and Mars. These planets have solid surfaces made mostly of rock and metal.
Which planet is the smallest of the gas giant planets?
Of the Jovian (gas giant) planets, Neptune is the smallest while Jupiter is the largest.
What planet is the smallest planet not including dwarf planet?
Mercury is one of the four inner terrestrial planets, or rocky planets. It is the smallest of the four and closest to the sun. It is also the smallest of all eight planets.
What is the smallest planet out of the four inner planets?

What is the smallest planet out of the 4 inner planets?
Mercury is the smallest planet out of the four inner planets in our solar system. It has a diameter of about 4,879 kilometers.
Why are the smallest planets the densest?
because they are made of mostly metal and rock while the bigger planets are mostly made of gas
Is Mercury a giant or a rocky terrestrial?
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
Is mercury a gas or a rocky terrestrial?
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
What is mercury planetary type?
It's one of the eight manor planets of our solar system, although the smallest. It is also one of the four inner rocky planets, or terrestrial planets.
How the inner planets are similar to each other?
The four inner planets are all made of rock or are rock based but the four outer planets are all made of gas or gas based.
What are the last four planets made of?
gases
What does the name gas giants suggest about four of the planets?
The planets are made out of gas.
Is Mercury a gas or rock planet?
The four planets which are closest to The Sun, which are Mercury, Venus, Earth and Mars, are all classed as rocky planets.
