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.
About Light Days
A light day (ld) is the distance light travels in one day through a vacuum, equal to approximately 25.9 billion kilometers. This unit bridges the gap between planetary distances and interstellar space. The Voyager 1 spacecraft, humanity's most distant object, is currently over 0.9 light days from Earth. The outer edge of our solar system (heliopause) is roughly 0.6-0.7 light days away. The Oort Cloud, a theoretical sphere of icy objects surrounding our solar system, extends from about 0.16 light days to possibly 1.6 light years.
