SOLAR SYSTEM

Detailed explanation-1: -Parsec is larger unit of the distance as compare to the light year. Thus, parsec is the larger unit of the distance than light year and one parsec is approximately 3.26158 times bigger than light year.

Detailed explanation-2: -This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37, 200 years to go one light-year.

Detailed explanation-3: -One gigaparsec (Gpc) is one billion parsecs-one of the largest units of length commonly used. One gigaparsec is about 3.26 billion ly, or roughly 114 of the distance to the horizon of the observable universe (dictated by the cosmic background radiation).

Detailed explanation-4: -Kilometers are the longest unit of metric measurement. The abbreviation for kilometers is km (for example, 12 km). Like miles, kilometers are used to measure long distances, such as the distance from your house to the store or from one town to another.
