Note that the light-year is a measure of distance. It is not a measure of time, for which it is sometimes mistaken. The closest star to earth other than our Sun is Alpha Centauri, which is 4. Because the speed of light is only , miles per second, it can only travel 6 trillion miles in one year. Therefore, it takes 4. We'd be better off with base 8 or base 16 than with base But base 60 comes in well before base 10 on the list of potentially useful systems.

This distance that causes a Parallax of one arcsecond is known as a Parsec. This distance is equal to 3. What unit is used to measure distance in space? What is Parallax in physics? How does Parsec work? Parsec is a desktop capturing application primarily used for cloud-based gaming through video streaming.

Using Parsec, a user can stream video game footage through an Internet connection, allowing one to run a game on PC but play it remotely. What is more than Lightyear?

A parsec measures 3. Other units are megaparsec which is one million paresecs and one lkiloparsec which is one thousand parsecs. It is aproximately 3. What is more than a Lightyear?

A parsec is greater. It is approximately equal to 3.
