Help me understand this.
Can someone explain this definition to me?
Main Entry: par·sec
Pronunciation: 'pär-"sek
Function: noun
Etymology: parallax + second
: a unit of measure for interstellar space equal to the distance to an object having a parallax of one second or to 3.26 light-years
I know it should probably be easy, but I'm just not catching it?
