Density of planets in our solar system

What is the average density of planets in order?

The average density of planets in order are:- Earth, Mercury, Venus, Mars, Neptune, Jupiter, Uranus, and Saturn. For reference (1 gm/cm3 = 1000 kg/m3). The density of water is almost 1 gm/cm3 or 997 kg/m3. Mercury is the second densest planet of our solar system after the Earth (5.514 gm/cm 3).

What is the density of Earth compared to giant planets?

Though its density increases with depth. The Crust density is almost 2.5-3.0 gm/cm 3, for Mantle 3.0-3.5 gm/cm 3, and the inner core density is approximate 13 gm/cm 3. So the mean density of the earth is 5.514 gm/cm 3. Mars is the least dense terrestrial planet. Though it has more density in comparison to giant planets.

What is the density of Jupiter vs Saturn?

Planet Jupiter is the 2nd densest giant-planet after Neptune. It is the largest planet but made of gases, so the density of this planet is lower. Saturn is the least dense planet in our solar system. The density of Saturn is just 0.687 gm/cm 3, which is less than the density of water (1 gm/cm 3).

What is the density of the Earth?

So the mean density of the earth is 5.514 gm/cm 3. Mars is the least dense terrestrial planet. Though it has more density in comparison to giant planets. Its atmosphere density is also lower, and the highest atmospheric density on Mars is almost the same as that found 32 km above the earth’s surface.

How do you calculate the density of a planet?

Density computed using the total volume and mass of the planet. Time required for a full rotation of the planet relate to fixed stars. Time required for the planet to make one complete orbit around the sun relative to fixed stars. The visual magitude of the planet as seen at a distance of 1 au from both the Sun and observer.

What is the average density of the Sun compared to Earth?

Compare to the earth’s average density (5.514 gm/cm 3) it just 0.255 times. But the center density of the sun is 162.2 gm/cm 3, which is almost 12.4 times of earth’s center density (13.1 gm/cm 3). This is the average density of the moon and it is almost 60.5% of the earth’s average density.
