Hai..
One 'parsec' is the distance from a star which makes an angle of 1''(1/60 of a degree)with the sun and earth(1.5*10^8 km).So by measuring an angle of 1'' we can measure to a maximum of 2 parsec.
But this only about 7 light years and we are speaking of much much bigger astronomical distances.How these are measured.
Thanks...
