Parsec is the unit of

Correct option is B

Correct Answer is (B) Distance

Explanation:

Parsec is a unit of distance used in astronomy to measure large distances to astronomical objects outside our solar system. One parsec is equivalent to approximately 3.26 light-years or about 3.09 × 10¹³ kilometers. The term "parsec" is derived from the combination of "parallax" and "arcsecond," and it is based on the concept of stellar parallax—the apparent shift in the position of a star when viewed from Earth at different points in its orbit.

Information Booster:

1. Parsec is used primarily to describe distances to stars, galaxies, and other celestial objects.

2. The distance of 1 parsec corresponds to the distance at which one astronomical unit subtends an angle of one arcsecond.

3. Astronomical Unit (AU) is the standard unit for measuring distances within our solar system, whereas the parsec is used for objects beyond the solar system.

4. Parsecs are particularly useful in measuring stellar distances where light years would be too large a unit.

5. The unit of parsec is integral to the field of astrophysics and cosmology.
