What are planets and stars different?
91699
Stars are burning like our sun. Planets aren't burning like our earth. Planets usually orbit around suns.

There are more stars than we can count.  Most of them have planets.   Most of those planets have moons.

planet= wanderer , because they appear to move different form the stars, that showed fixed patterns.

the system of a star called sun is is called Solar system.....\nall the systems of stars with planets around them are not solar systems.\nSolar system is name of our sun planets system

Venus, or jupiter. Find a fixed star close to the planet in question. If it moves relative to that star the next day, then it is Venus. If it takes a few days to notice movement, then it is jupiter. The planets closer to the sun will move faster to relative objects in the sky, those farther out will move slower....KECK

well stars are in real more like our sun which gives heat and light, but y they have diff color id coz AS ALL THE STARS ARE NOT AT THE SAME DISTANCE FRM THE EARTH THE LIGHT WHICH TRAVELLS FRM THEM AND REACHES US GIVE THEm COLOR .\n\nLIKE white light has 7 colors in it and each has different wave lenght which means that their light travels on those wave lenghts, and secondly the air in our atmosphere water particles are suspended always and these light passing through them give different wave lenght wch gives us diff color

With this information contained...no wonder not anyone really has a handle on the exact definition of a planet.  It will be debated for a long time.\n\n# (astronomy) any of the nine large celestial bodies in the solar system that revolve around the sun and shine by reflected light; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto in order of their proximity to the sun; viewed from the constellation Hercules, all the planets rotate around the sun in a counterclockwise direction\n# satellite: a person who follows or serves another\n# any celestial body (other than comets or satellites) that revolves around a star\nwordnet.princeton.edu/perl/webwn\n\n# A planet (from the Greek πλανήτης, planētēs which means "wanderer" or more forcefully "vagrant, tramp") is an object in orbit around a star that is not a star in its own right.

This is somewhat ambiguous. In our solar system it is really an historical definition which boils down to "a planet is a member of the set {Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto}". All the known planets orbiting other stars are large gas planets so no ambiguity yet arises there. ...\nwww.astro.uio.no/ita/TNP/nineplanets/help.html\n\n# is the term used for a body in orbit around the Sun.

Yes, the planets go through phases. Celestial phases are basically light hitting different hemispheres at different times.

Twertyto's answer is the best! When I was just learning about astronomy I asked the same question. Someone told me a very simple answer that just might work for you:  A planet reflects light and a star creates it. That sounds simple enough for simpler times! But now welcome to the 21st century!!!\nBrown dwarfs are kind of the "animal" that bridges these two seemingly different objects. Astronomy is having a hard (but fun) time right now trying to decide exactly what a planet is- from the very large to the very small. Is an object 75 times the size of Jupiter a planet? 79 times? 81 times? No one seems to know. Do we call them planets or officially name them Brown Dwarfs. On the other side of the issue, is Pluto a planet? They just discovered a larger than Pluto object and several almost-the-size-of-Pluto objects out past Pluto's orbit. Are all of these planets? If Pluto's not a planet, but now has been discovered to have at least 3 moons (two new one's were just discovered recently), then what do we call it? \nThis has been a surprisingly tough answer for Astronomers as well, so not only is it a great question, but you- and everyone else- might have to stick around for a while for the difinitive answer!!!

stars are very far away and that light u see has been traveling through space for maybe decades now and its passed through clouds of dust and a bunch of stuff.  That makes the star twinkle and gives it colors.  Also, stars are not white(unless they are white dwarfs, but those arnt really stars or they are really really big and hot).  Almost all stars have a color to them.  These can be blue, red, yellow, orange, or any of those colors inbetween.

no, astronomers are trying to define what a planet is, but it isn't easy.  many astronomers favor the reclassification of the bodies in the solar system into three groups, the rocky terrestrials, the gas giants, and the ice dwarfs.  there are four rocky terrestrials and four gas giants, but there are hundreds of known ice dwarfs. this is called the kuiper belt.  kuiper belt objects are bodies like pluto, quaoar, sedna, 2003 UB313, and 2003 EL61.  2003 UB313 (the official name of xena) is about five percent bigger than pluto, but pluto was the first kuiper belt object discovered.\n\nread this page:\nhttp://en.wikipedia.org/wiki/Kuiper_belt

Nice question....stars shine because it is millions of light year away from us...in the case of planets its nearer than stars...not sure though..but i think so...

Stars don't move our sun is a big star it is our planet that orbits our star so that is why it seems like the stars move my lov.

Stars, except for the Sun, although they may be millions of miles in diameter, are very far away.  They appear as point sources even when viewed by telescopes.  The planets in our solar system, much smaller than stars, are closer and can be resolved as disks with a little bit of magnification (field binoculars, for example).\n\nSince the Earth's atmosphere is turbulent, all images viewed up through it tend to "swim."  The result of this is that sometimes a single point in object space gets mapped to two or more points in image space, and also sometimes a single point in object space does not get mapped into any point in image space.  When a star's single point in object space fails to map to at least one point in image space, the star seems to disappear temporarily.  This does not mean the star's light is lost for that moment.  It just means that it didn't get to your eye, it went somewhere else.\n\nSince planets represent several points in object space, it is highly likely that one or more points in the planet's object space get mapped to a points in image space, and the planet's image never winks out.  Each individual ray is twinkling away as badly as any star, but when all of those individual rays are viewed together, the next effect is averaged out to something considerably steadier.\n\nThe result is that stars tend to twinkle, and planets do not.  Other extended objects in space, even very far ones like nebulae, do not twinkle if they are sufficiently large that they have non-zero apparent diameter when viewed from the Earth.

That is because like our solar system, other systems are diverse in birth and formation. There are many classes of stars that go through different phases. These phases will determine how many planets, asteroids, comets and planetoids a star has. Some major factors that decide this are:\n1. Amount of material and how much the star uses\n2. The amount of gravity the star posesses (Material will float away from it and in time orbit it.)\n3. The behavior of the star (Does it like to swell 60 times its original size every 200 million years? That would surely destroy any planets.)

Senda - smaller than pluto, not a planet.\n2003 UB313 - bigger than pluto, not a planet\n\nThere are lots of objects just like Pluto out there, but right now it is a "planet" and the others are not.  The IAU's Division of Planetary Science is currently working on the whole planet issue, and we are supposed to have some sort of resolution to this issue by august of this year.  It is actually quite a mess over at the IAU right now.\n\nAs far as the universe goes?  We have found almost 200 objects that we call planets, but they are orbiting other stars.

Chance.\n\nMany stars in the galaxy are part of binary systems.  As the gaseous nebula that forms a solar system collapses, the mass can distribute in many ways.  The Sun got the majority of the mass, and Jupiter carries much of the residual mass of the solar system (2.5x the mass of the other planets).  If more mass had gone to Jupiter, we might be in a binary solar system.  If the majority of the mass went to Jupiter, it would be the Sun, and vice versa.
