The Planets in our Solar System (if I am reading your question correctly)Order of Planets in our Solar System (from closest to the Sun, out):MercuryVenusEarthMarsSaturnJupiterNeptuneUranus*(NOT PLUTO ANY Longer, since it was DEMOTED to a PLANETOID)
Of the planets of our solar system, only Earth itself is easy to live on. None of the other planets are habitable without a protective sealed habitat. Of the other planets, Mars may be easiest; we'll need to build the sealed habitat, and convert some of the iron oxide in the soil to oxygen that we can breathe, but it won't be INCREDIBLY cold, or have poisonous atmosphere, or crushing pressure. And after we've figured out how to live on the Moon, Mars will be fairly straightforward.
Yes, scientists use telescopes and space probes to analyze the composition of different planets. By studying the light that reaches us from these planets, scientists can determine the elements present in their atmosphere and surface materials.
All masses attract one another. Do some reading about the general law of gravitation for more information.
The same factors that determine the force of gravity between ANY objects. (1) The masses involved, (2) the distance between the masses.
the effect it has on other planets
The masses of Mercury and Venus were unknown for so long because they do not have any moons orbiting them, which makes it difficult to measure their masses using traditional techniques like gravitational interactions with moons. Instead, scientists had to rely on more indirect methods, such as measuring the orbits of spacecraft exploring these planets or using radar measurements to estimate their masses.
They are all solid masses, i.e. not gaseous bodies like the outer planets.
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
But you CAN determine the size of the planets: in diameter, overall mass, and in density.
The forces of gravity between two masses are the cause of all orbits.
Planets
They all have mass, and masses are attracted to each other.
The outer planets are primarily gaseous meaning they are basically just gargantuan masses of gas.
Jupiter
Yes, any planet can have satellites. Gas planets actually have the most satellites due to their large masses.
they are all soild masses and mecury, venus, earth, mars
