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 Light Minutes

A light minute (lm) is the distance light travels in one minute through a vacuum, equal to 17,987,547,480 meters or about 17.99 million kilometers. The Sun is approximately 8.3 light minutes from Earth, meaning sunlight takes 8 minutes and 20 seconds to reach us. Venus ranges from 2 to 14 light minutes from Earth depending on orbital positions. This unit provides a convenient scale for discussing distances within the inner solar system and helps visualize the time delays in space communications.
