About Light Hours
A light hour (lh) is the distance light travels in one hour through a vacuum, approximately 1.08 billion kilometers. Jupiter is about 0.72 light hours from the Sun, while Saturn orbits at roughly 1.3 light hours. This unit is useful for expressing distances to the outer planets and understanding communication delays with spacecraft. A radio signal to a probe near Jupiter takes about 43 minutes to arrive, representing the vast scales even within our solar system. Pluto at its farthest reaches about 5.5 light hours from the Sun.
About Gigaparsecs
A gigaparsec (Gpc) is one billion parsecs or 3.26 billion light years, used for measuring the largest structures in the cosmos. The observable universe has a radius of about 14.3 gigaparsecs (46 billion light years when accounting for expansion). Superclusters and cosmic filaments, the largest known structures, span hundreds of megaparsecs to gigaparsecs. The cosmic microwave background radiation originates from a distance of about 14 gigaparsecs. This unit helps cosmologists map the large-scale structure of the universe and understand its evolution since the Big Bang.
