What do astronomers use to determine the difference between rocky and gaseous planets?

Average density of the planet


Which planet has the lowest average density?

Saturn:)Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water)


Between Mercury Jupiter Venus and Mars which planet has the lowest density?

I would think that of these Jupiter would have the lowest density, since Mercury, Venus and Mars are all solid, rocky planets like Earth while Jupiter is a gas giant composed mainly of Hydrogen.


What does the least dense planet mean?

The phrase "least dense planet" refers simply to the planet with the lowest density, which is the planet's mass divided by its volume. In our solar system, Saturn is the least dense planet with a density of roughly 0.7 (water, by comparison, has a density of 1, or 1 gram per cubic centimeter). This is attributed to its large outer envelope of gas - although it is thought to have a denser rocky core.


Which planet in your solar system has the greatest density?

Mercury comes in 2nd place - average density (5.44 g/cm3 == ==


Is planet Mars the densest planet?

Not at all. Mars is the least dense of the rocky planets. Earth is the densest planet in the Solar System because of its large iron core. Mercury and Venus are only slightly less dense.All of the Gas giants are much less dense than the rocky planets. The least dense, Saturn, is actually less dense than water. (All of the gas giants have a much greater mass than the rocky planets but density is mass divided by volume)


What planet is not small and rocky?

The least small and least rocky planet is probably Saturn. Saturn - as a whole planet - has a density less than water, meaning that if you could find a lake big enough to put it in, Saturn would float!


Is mars a rocky planet or a planet?

Which type of planet will have a higher overall density?

A rocky planet will typically have a higher overall density compared to a gaseous planet. This is because rocky planets are composed of heavier elements like iron and silicate minerals, while gaseous planets are primarily made up of lighter elements like hydrogen and helium.

What parameters can tell you about a planet's composition?

Parameters such as mass, radius, and density can provide clues about a planet's composition. For example, a high density suggests a rocky composition, while a low density suggests a more gas-rich composition. Additionally, spectroscopy can be used to analyze the planet's atmosphere and determine the presence of certain elements or compounds.
