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.

About Terameters

A terameter (Tm) is one trillion meters (10¹² m), representing distances within our solar system. The distance from the Sun to Mars ranges from about 0.08 to 0.4 Tm depending on orbital positions, while Jupiter orbits at approximately 0.78 Tm from the Sun. Pluto, at its farthest, is about 7.3 Tm from the Sun. This unit is essential in planetary science and space exploration for expressing interplanetary distances without resorting to even larger astronomical units.
