Yogita Ingle 7 years, 4 months ago

The parsec is a unit of length used to measure large distances to astronomical objects outside the Solar System .
The unit of 'parsec' is defined so that if the parallax angle is measured in arcseconds from the Earth at six month intervals, the distance to the star is in parsecs .

1 parsec=206,265 AU
1 parsec=3.0857X10¹⁶ m
1 parsec=3.2616 light years
