Answer 1

Answer:

Parsec, unit for expressing distances to stars and galaxies, used by professional astronomers.

Explanation:

* Light year = Distance travelled by light in one year in vaccum.

* 1 light year = 9.46×10^15 m

* 1 astronomical unit (A.U) = 1.5×10^11 m.

* 1parsec = 3.26 light year = 3.08×10^16 m.

Answer 2

parsec

• The parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years or 206,000 astronomical units, i.e. 30.9 trillion kilometre

• One parsec is approximately equal to 3.26 light-years. Proxima Centauri, the nearest known star to earth other than the sun, is about 1.3 parsecs (4.24 ly) away, by direct parallax measurement
