Different planets are made up of different materials, and they are different masses. Some planets are made up of gases, they are called Jovian Planets. And some planets, the terrestrial, are made of solid rock or particles. It just depends on what they are made up of (:
The relative masses of planets is irrelevant - a litre of water has the same density as a millilitre. However, there are other factors to take into account - temperature and pressure. Heat a substance and it will expand but its mass will remain the same, i.e. its density will decrease. Compress a substance and it will contract, i.e. its density will increase.
Although the Earth is the densest planet, after Mercury, if Mercury was the same size as the Earth, Mercury would be the most dense. The Earth achieves this because of gravitational compression, where the gravity of Earth compresses the outer materials.
What else can I help you with?
Is Pluto denser than the terrestrial planets?
No. Pluto is significantly less dense than the terrestrial planets. A large portion of Pluto is made of ice, which is less dense than thr eock and metal that compose the terrestrial planets.
Why do some planets take longer to orbit the sun than others?
Planets further out from the sun have a larger orbit to travel around, which takes more time. This is because their orbital path is longer, meaning they move at a slower average speed compared to planets closer to the sun. This results in different orbital periods for different planets.
Do other planets rotate?
Yes, some faster than others. In fact, virtually all spacial bodies rotate.
Which planet rotates on its axis?
All of them, though some more slowly than others.
The Earth is the densest planet in the Solar System Is it denser or less dense than water?
Earth is more than 5 times denser than water. Of all the planets in the solar system, only Saturn is less dense than water.
How are the planets classifications as a terrestrial plaent or gas giant generally related to their densities?
Rocky planets are denser than gas giants.
Are outer planets denser than smaller planets?
No. The outer planets are gas planets, which are much less dense than the inner terrestrial planets.
How many planets in your solar system are denser than earth?
there 9 planets one is moved
Why are some planets bigger than other?
because when god made the planets he made explosions everywhere to make planets. some explosions were bigger than others.
Do denser planets have larger orbits in the solar system?
no, then inner solid planets are more dense than the outer gas planets
Is the average density of terrestrial planets the same density as Jovian planet?
No. Terrestrial planets are much denser than Jovian planets.
What is the difference and similarities in the planets?
Some are colder than others and some have rings around them
. In the electron cloud model the electron cloud is denser in some locations than in others. What do the denser areas represent?
Regions where the probability of finding an electron is high.
Why do some objects float and others do not?
because some objects are much denser(heavier) than water so they sink
Are the planets that are closer to the sun denser?
Roughly speaking, yes: the four inner planets are quite a lot denser than the four outer planets, which are gas giants. However, note that the densest planet is Earth, which is planet #3.
What causes objects to be denser than others?
Atoms cause the objects to be denser when they are more compact it's denser and more spread out it's not denser
Why do some objects float and others dont?
Because some objects are a lot denser than water so the sink and others are less denser so they float
