What is Astronomical unit?

Astronomical unit (au): Used for distances within the Solar System. It represents the scale of the Earth–Sun distance but has an exact defined value, not the changing distance on a particular day. 1 au = 149597870700 m.

What is Parsec?

Parsec (pc): An astronomical distance unit of about 3.26 light-years. Kiloparsecs and megaparsecs are used for larger distances between stars and galaxies. 1 pc ≈ 3.0856775814914 × 10¹⁶ m ≈ 3.26156 ly.
