Answer:
The name of the fundamental quantity is distance.
Explanation:
- The distance at which one astronomical unit subtends an angle of one arcsecond, or 3.26 light years, is known as a parallactic second, also known as a parsec.
- Light travels across a distance of one light year per year. Given how quickly light travels, that is a considerable distance. Light years are roughly six trillion miles long. The average distance between the earth and the sun is measured in astronomical units. Consequently, the distance to the sun is one AU by definition.
- A light year is the distance that light covers in one Earth year. In addition to being used for measurements inside the solar system, the parsec is also a unit of measurement. A parsec is a unit of measurement for distance.
Thus, AU, parsec and light year are the units of distance quantity.
