From our vantage point here on Earth we can see light from stars that are billions of light-years away. The light-year we have already defined. The next nearest star is Alpha Centauri, a triple-star system visible from the southern hemisphere, four light-years away. Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth. At around 900 light-years from Sol, Mebsuta (Epsilon Geminorum) is a relatively close example of a rare G-type supergiant, with seven to nine Solar-masses and a luminosity of around 7,600 times that of the Sun. G-type supergiants can have more than nine solar-masses and a luminosity that can reach more than 10,000 times that of the Sun. The nearest known star (other than the Sun), Proxima Centauri is 4.22 light years away. But, I am sure you are wondering how in the world we go 3.26 light years per parsec! A parsec is a measure of distance. Scaling the Earth-sun distance at one inch places this star at 4.4 miles (7 km) distant. You can just put ''distance to the moon in light years'' and answer comes up. A light year is 9,460,730,472,580.8 kilometres, which is a vast distance, and an expression of the distance between these two planets in light years would be too small to handle easily.

So, the simple answer to your question is a simple multiplication problem. If you are asking the distance between the nearest sun from our earth I.e the the distance between our sun and earth is 93 million miles, which is very much fraction when converted to light years and is 0.00001581 light years. Proxima Centauri is about 262,000 times farther away from us than the Sun.) For example, the nearest star system to ours is the triple star system of Alpha Centauri, at about 4.3 light years away. Something that is one parsec away is 3.26 light years away. Some 53 stellar systems beyond our own, the Solar System, currently lie within 5.0 parsecs (16.3 light-years) of the Sun.These systems contain a total of 63 stars, of which 50 are red dwarfs, by far the most common type of star in the Milky Way.Much more massive stars, such as our own, make up the remaining 13. All of these stars are bright giant and supergiant stars, thousands of times more luminous than the Sun. A MYSTERIOUS object 500million light years away has baffled scientists after transmitting signals that hit Earth every 16 days. The Sun creates daylight on Earth. The closest star to Earth, other than the sun, is Alpha Centauri at some 4.4 light-years away. However, it takes a very long time for the light inside the sun to get out, something like a million years i think, so the light you see from the sun took eight minutes to reach you from the surface of the sun, but countless thousands of years … It is actually a triple star system made up of Centauri A, Centauri B, and Proxima Centauri (Centauri C). A light-year is the distance that light travels in one year (365 days). Galaxy M 89, 60 million light years away. The Solar System: The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. The nearest star beyond the sun is Alpha Centauri, 4.2 x 1016 meters away. If the Sun were viewed from this distance it would appear over 300 times fainter than Sirius (the brightest star in our nighttime sky) appears to us on Earth. Once again a homework question on Quora. But now I have to write something extra here because just like your stupid question, Quora's bot is also stupid. The sun is eight minutes away at the speed of light. A new study from the Georgia Institute of Technology provides new clues indicating that an exoplanet 500 light-years away is much like Earth. It is reasonable, therefore, to assume that our universe is at least billions of years old—old enough to give the light from these stars enough time to reach our planet billions of light-years away. That's a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU. The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. The Sun is the star at the center of the Solar System.It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as light and infrared radiation. The Milky Way Galaxy is about 150,000 light-years across. Centauri A is a little bit bigger than our sun, Centauri B is a little bit smaller than the sun, and Proxima Centauri (Centauri C) is a lot smaller than the sun. Every star within 15 light-years from the Sun is a dwarf! We do, however, see a run-of-the-mill A star, Sirius, the brightest star in the night sky. For instance, Mercury is the closest planet to the sun. “Mirror Image” of the Earth and Sun Discovered 3000 Light-Years Away . They're just not far enough away.
