IPA: /ˌkɪləˈpɑːrˌsɛk/
KK: /kɪloʊˈpɑːrˌsɛk/
A unit of measurement for distance in astronomy, equal to one thousand parsecs.
The nearest star is about 1.3 kiloparsecs away from Earth.
Kiloparsec → It is formed from "kilo-" (from Greek "chilioi", meaning thousand) and "parsec" (from "parallax" and "second", referring to a unit of distance based on the apparent shift of an object against a distant background). A kiloparsec is therefore a distance of one thousand parsecs.
Think of 'kilo-' meaning a thousand, and 'parsec' being a unit of distance based on parallax. This helps you remember that a kiloparsec is a distance of one thousand parsecs.
