First of all we all live on a planet. Astronomers study planets because they usually represent approximations of the early Earth and they help us understand the formation of the Solar System.
The planets are the repository of 98% of the angular momentum in the solar system. If all the planets were collapsed into the Sun it would rotate 50 times faster and perhaps throw off a new disk that would condense into more planets.
Anyway a planet is somewhere to live, I suppose.
there are so many planets because,well let me phrase it like a story,the planets are basicly the galaxies babies,but those babies have more babies constantly,the babies that were born from the other babies are called meoterors,over time meoteors grow bigger,then finaly they have babies!YOUR WELCOME!XD
Because planets are chunks of matter left over from explotions, collisions, etc. Eventually, the gravitational pull of something , such as our sun, catches the planet an it orbits around the sun. Wala, a planet.
The Solar System have today ONLY eight planets because all other planets, and protoplanets, formed during tens of millions years after the Sun had begun its life as a T Taury star, were mutually destroyed by gigantic collisions.
During many millions of years, the Solar system was very much like a cosmic billiard table: every recently formed body collided - with moderate to extreme violence - with other bodies.
A great number of planets and planetesimals (many astronomers belive our stellar system had, in the first stages of formation, several hundereds of planetary bodies), were totally destroyed and formed what it would became much later the Asteroid Belt and/or the Kuiper Belt.
Other bodies collided and formed other different planets (the case of the primordial Earth and a Mars-sized planet collision creating the binary system Earth/Moon).
There were MIGRATIONS of planets (including jovian planets) from the Sun's neighbour to outer solar system, and vice-versa, causing bizarre anomalies in all planet's orbits.
Some planets were simply gravitationally thrown out to the Kuiper Belt (such as the trans-Neptunian objects like Sedna and Eris), eventually to extremely eccentric orbits in the Oort Cloud or even expelled for ever from the solar system, becaming «rogue planets».
Planets were made by God and that is why we have them. Not by our own will.
They just are. Theres nothing you can do about it.
we have planets because that god made them and we wouldn't have earth.
Most astronomical matters do not lend themselves to "why"-type questions. We observe that things ARE; sometimes it's not clear "why".
The planets closer to the Sun than Jupiter are: Mercury, Venus, Earth, and Mars. So, four planets are closer than Jupiter.
There are 8 planets.
So far we know of only one planet that is habitable.
many people think there are 8 planets, 9 planets or 10 planets in our solar system. 8 planets is the well accepted fact by most scientist, this means pluto is not a planet, many however believe it is so they think there are 9 planets, and some believe there are 10 planets, a so called planet X that will come close enough to earth to disrupt the gravity field and cause solar rays to greatly affect us, but this has never been proven
There are 7 main classification of Planets. They are classified into the following groups; * Inferior Planets * Superior Planets * Inner Planets * Outer Planets * Terrestial Planets, * Jovian Planets * Gas Giants
the Earth is a planet so it can't have more planets!
mercury, venus, earth, mars. so 4.
Nobody knows for sure, but there is so many, that there might be more planets than people on earth!
You are very stupid.
It would be almost impossible to calculate the diameter of all the planets in inches, so your question can't really be answered. Plus, there are so many planets out there, so even calculating that in miles or kilometers would be pretty much impossible.
they are so many km away
nine planets till 2006 until Pluto was broken down so there was only eight planets in the solar system '
There are about 480 which have been discovered so far in the universe a handful of them are dwarf planets. Hope this helps!!!!
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
There would be 21 planets because there is 6 planets not counting Pluto since it is a dwarf planet and so 9+12=21 so remember Pluto is a dwarf planet
8 planets and 5 dwarf planets, so 13 in total. There are some additional dwarf planet candidates that have not been officially categorised yet.
The planets closer to the Sun than Jupiter are: Mercury, Venus, Earth, and Mars. So, four planets are closer than Jupiter.
