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 Gigameters
A gigameter (Gm) is one billion meters (10⁹ m), making it useful for planetary measurements and inner solar system distances. The Sun's diameter is about 1.39 Gm, while Jupiter's diameter is roughly 0.14 Gm. The distance from Earth to the Moon is approximately 0.38 Gm. This unit bridges the gap between terrestrial measurements (megameters) and astronomical distances, providing a convenient scale for describing planetary sizes and nearby celestial distances in our solar system.
