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.
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.
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.
Yes, some faster than others. In fact, virtually all spacial bodies rotate.
All of them, though some more slowly than others.
Earth is more than 5 times denser than water. Of all the planets in the solar system, only Saturn is less dense than water.
Rocky planets are denser than gas giants.
No. The outer planets are gas planets, which are much less dense than the inner terrestrial planets.
there 9 planets one is moved
because when god made the planets he made explosions everywhere to make planets. some explosions were bigger than others.
no, then inner solid planets are more dense than the outer gas planets
No. Terrestrial planets are much denser than Jovian planets.
Some are colder than others and some have rings around them
Regions where the probability of finding an electron is high.
because some objects are much denser(heavier) than water so they sink
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.
Atoms cause the objects to be denser when they are more compact it's denser and more spread out it's not denser
Because some objects are a lot denser than water so the sink and others are less denser so they float
