No, size does not go with density. The Earth is the most dense planet in the solar system, but it is the 4th smallest planet.
Size is a relative concept. The Earth is very big in comparison to me. The Earth is very small in comparison to the Milky Way galaxy.
U can group the planets by size,weight and amount of moons
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. Of these four, the largest and the most massive is the Earth.
Moons are larger, obviously.
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.
The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.
Earth is a fairly small planet. It is neither the biggest nor the smallest, as there are literally billions of billions of planets.
Mercury is the smallest. It's slightly bigger than the moon.
The 4 smallest planets are also the 4 most inner planets: Mercury, Venus, Earth and Mars.
Mercury is the smallest of the terrestrial planets.The others in order after Mercury:MarsVenusEarth
Planets from smallest to largest: Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter Mercury is the smallest planet Jupiter is the largest planet
Mars is the second-smallest major planet (Only Mercury is smaller).Planets in order of size, smallest to largest :MercuryMarsVenusEarthNeptuneUranusSaturnJupiter(see related link)
Largest and smallest are both size descriptors so you have to look at their size before putting them in the order of largest to smallest. It's the only way to do it.
Referring to the actual 8 designated "planets", the closest four to the Sun are smaller and rocky, while the outer four are gas giants. Planets in order of size (smallest to largest): Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter.
All four rocky planets are much smaller than gas planets.
Mercury is both the smallest inner panet, and the smallest planet in our entire solar system.
