All of them do.
As compared to Earth the density of URANUS is less, since Uranus is one among the gaseous planets.
Much less than that of Earth. For example, Saturn's density is less than that of water; Jupiter's density is slightly larger than that of water.
No, the density of Mars is less than that of Earth and Venus, making it less dense than other terrestrial planets. This lower density is due to Mars having a smaller iron core and less overall mass compared to Earth and Venus.
The average density of the terrestrial planets is greater than the density of Earth's crust. Terrestrial planets have higher densities due to their composition of rock and metal, while Earth's crust is composed of lighter minerals like granite and basalt.
gravitational pull depends on density and mass.
The planets that have less mass than Earth are Mercury, Mars and Venus. The planets that have a lower average density than Earth are all of them; Earth is the most dense planet in our solar system.
It is said that if you could find an ocean on Earth large enough to accommodate it, Saturn would float. That is, Saturn's average density is less than the density of water. Turns out it's the only planet with an average density less than 1.000, that is, less than the density of water.
Less
they are gas, and gas is less dense
Yes, the Earth's moon is less dense than Mercury. Mercury is one of the densest planets in the solar system, with a density about 5.4 times that of water, whereas the Moon has a density about 3.3 times that of water.
Earth is the most dense of the planets, at 5.51 gm/cm3 .Saturn's density is 0.687 gm/cm3 ... about 12.5%of Earth's density,and less than the density of water. Which means that if you could findan ocean big enough, Saturn would float in it.
Yes. It has no iron core.
