the distance of the whole solar system in light years?
139145
The earth is one AU from the sun.  One AU is 93 million miles.  The diameter of the solar system is 80 AU.  There are about 6 trillion miles in a light year.  The speed of light is 186,000 miles per second.\n\nPerforming the math.  The solar system has a diameter of .0012 light years.\n\nThe .0012 is derived from the following equeation - 93 million miles times 80AU divided by (186000 miles per second times (365 days times 24 hours times 60 minutes times sixty seconds).

Proxima Centuri. About 4.2 light years away. Check the foll link for more info\n\nst

There is no actual picture of the entire solar system. If one could be made, it is very unlikely that you would be able to see all the planets. I am sure you would only see The gas giants Jupiter and Saturn - as dots; maybe you will see Neptune and Uranus, that is about it. From earth if you look at Jupiter in the night sky it is as big as a star - though one of the brightest objects in night sky. From a position where you could see all the planets (the solar system is bigger than that, but let us restrict ourselves to only Pluto's orbit) you would see it as much smaller. Jupiter is 1,600 times bigger than earth (volume). Sun is a million times bigger. From most cities you can see Mars, Saturn, Jupiter and Venus. From a position where you could take a picture of all the planets you wont see all of them.\n\nEDIT: btw, I just remember I was talking about visibility of sun and planets. Actually if a photograph were taken jupiter and sun will be visible. The Sun is a star it will be visible not due to its size but due to the amount of light it gives. If we plotted it on a graph based only on its size and not its luminosity, it will be as visible as anything on the graph and no more. So if we drew an illustration 1024 pixels wide (most 17 inch computer screens are 1024x768 pixels) and put sun on the left most pixel and Neptune on the right most pixel - none of them will be visible. The distance between sun and earth is 1 AU (1 astronomical unit). Sun's Diameter is 1/150 AU, Neptune is 30 AU away from sun. If we scale 30AU to a 1024 pixel screen every pixel is equal to 0.029 AU, anything smaller than 0.029 AU can not be represented on this screen, the sun is 0.006AU wide - 1/5th of a pixel. If you open MS Paint and put a dot with a pencil that is one pixel imagine 1/5th of that - that is sun's size scalled to a 1024x768 screen.\n\nAnyway, Cronides' second link is the answer you are looking for.

Despite it sounding like time, light year measures distance.\nIt's the distance that light travels in space in one year, a very long distance.\n\n186000*365*24*3600 = 5.87 x 10^12 miles.

About 93 million miles.  It's a distance used to measure distance of certain space objects.  It is called 1 AU or Astonomical Unit.\n\nIt is NOT 1 light year.  It's actually about 8 light minutes.

A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers.\n\nWhy would you want such a big unit of distance? Well, on Earth, a kilometer may be just fine. It is a few hundred kilometers from New York City to Washington, DC; it is a few thousand kilometers from California to Maine. In the Universe, the kilometer is just too small to be useful. For example, the distance to the next nearest big galaxy, the Andromeda Galaxy, is 21 quintillion km. That's 21,000,000,000,000,000,000 km. This is a number so large that it becomes hard to write and hard to interpret. So astronomers use other units of distance.

Relatively speaking, If you look at the center of the galaxy as a major city, we are way out in the country, far away. \nThe Sun (and therefore the Earth and Solar System) may be found close to the inner rim of the Orion Arm, in the Local Fluff, at a distance of 7.94±0.42 kpc from the Galactic Center.\nIt takes the solar system about 225-250 million years to complete one orbit (a galactic year),[14] and so is thought to have completed about 20-25 orbits during its lifetime.

Andromeda is just 2.5 million light years away.\nOur sun is only halfway through it's 4.6 BILLION year life.\nSolar systems closer to the Shapley Center of our Milky Way galaxy are younger.

Polaris is approximately 430 light years away. The earth as moves around the sun moves about 17 light minutes. So Polaris appears to move a little during the year but the amount is so small that it's not very noticeable.\n\nAdditional: Or to put it another way, it's like trying to tell if something 200 miles away moved about an inch.

A light year is a measurement of distance, not time.  It's the distance light travels in a year.  For example it takes light about 8 minutes to get from the Sun to the Earth.  Alpha Centauri (the next nearest star) is 4 light years away.\n\nA light year is 9.4605284 × 10^15 meters (10^15 means 10 to the 15th power).  Basically, it's REALLY far and only good for measuring huge distances in space.

light years isn't a time, it is a distance \nso it would be 2 light years

870436 billion light years. If u disagree, go and measure it urself

A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.

Currently, the accepted view is that the universe is approximately 78 billion light-years in size. A light-year is the distance light travels in one year (a large number since light travels about 186,000 miles each second). To determine this, astronomers used the WMAP project. See the links to determine how this was accomplished, but only if you don't mind being confused (it is quite lengthy and quite confusing - even for an astronomer such as myself!).

The universe in which we live is about 156 billion light years across.  Source: news.bbc.co.uk/1/hi/sci/tech/3753115.stm  Whats beyond that, good luck

I believe all the planets in our solar system formed about the same time, around 5 and a half billion years ago or so. I believe there is a younger solar system than ours around the star called Vega. It is in our galaxy and I believe it is around 26 light years away, the speed of light being 186,000 miles a second. The distance is the number of miles light would travel in 26 years, if that makes any sense. Vega is a blue star, a very young star. Our sun is a G star, a bit older. The stars are categorized O,B,A,F,G,K,M. The way to remember is the phrase "Oh, be a fine girl kiss me" with each letter corresponding to star categories. Vega is an O star, the youngest. I hope that isn't too complicated, I know your six.\n\nWhat you might do is get some colored balls to represent each of the star categories, some paint (in case the ball is the wrong color), and some cardboard, sticks, and glue. The M star is a red supergiant so a red dodge ball, the K is a red giant but not supergiant, so a red delicious apple, the O is blue-white, the G is golden, yellow-orange like our sun. The B, A, and F stars I do not know much about.

solar system I guess? 312.500.000 km, but there is no planet at such distance...what is it?\n\nasteroid belt...\n\n6  1/4=6.25\n6.25 x 200,000,000 / 4 = 312,500,000
