Planets generally orbit around stars. (Some interesting speculations suggest that there may be "free planets" that are not near any star.) Billions of these solar systems orbiting their common center of gravity form a galaxy.
A star is like our sun, a body with continuing atomic activity causing it to be very hot. A planet is a body either of solid material or gas that is in orbit revolving around a sun. Looking up into the night sky you will notice that planets do not blink or twinkle. Stars continuously twinkle. Stars are large and gaseous (except neutron stars or other special stars). The gravitational collapse of the material forming the star causes it to heat up, producing light via nuclear fusion. Stars therefore shine by their own internal fusion fire.
Planets are not big enough to produce light in this manner. If they appear bright, it is because they shine with the reflected light from stars (such as our sun). In our solar system, the planets appear to wander across the sky. Hence, the name "planet," which in Greek meant "wanderer." The stars, in contrast, are so far away their position appears fixed.
If you look at the way the earth orbits the sun you will see several physics theories and systems at work. The earth maintains a constant velocity that allows it to keep from falling into the sun's massive gravitational pull, and while the earth is revolving around the sun, it is rotating on its own axis, which gives us our tides (the moon also plays a part in the tides). Also, if the sun were to suddenly gain or lose mass or gravity the earth would catapult into nothing and we would freeze, this is just one small little example of how physics is related to planetary science.
the study of the planets and how they formed and where they are located are all about science
Its made of ice cream and mutant ninja turtles.
Their masses, and the power gravity of the Sun, make them perfectly related one to another, thus maintaing a precise distance among them.
They're both made of matter,for starters.
Jupiter has the shortest "day" of any planet in the solar system.
concentrate in one planet and if you already master it move on to another planet
There is a major difference from our planet and the other which is that our planet is the only one that is habitable for life
It's a matter of categorizing the different objects in the solar system.
No. It is a planet in another solar system about 500 light-years from Earth in the constellation Cygnus.

It is the third largest planet in our Solar system.
That star would be the sun. That's why it's a planet in our solar system.
Since this planet is a closed system recycling utilises the limited resources more efficiently.

Uranus. The seventh planet in our solar system is Uranus.
