How many light years away is sun
WebWe can measure the distance with this method using different units, but the most commonly used one is a parsec. One parsec is the distance from the Sun to the star under consideration when the parallax angle is equal to 1 arcsecond. Light years are another measure (1 parsec = 3.26 light-years), but this unit is more commonly used by the media.
