Answer 2

Answer:

1 parsec = 3.0857×10¹⁶ m

1 light Year = 9.4607×10¹⁵ m

Explanation:

For measuring long distances we can use PARSEC  or LIGHT YEAR as a unit.

The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System

1 pc = 3.0857×10¹⁶ m

The light-year is a unit of length used to express astronomical distances and measures about 9.46 trillion kilometres.

1 light Year = 9.4607×10¹⁵ m
