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 Attometers

An attometer (am) is one quintillionth of a meter (10⁻¹⁸ m), smaller than atomic nuclei but larger than the realm of pure theory. This scale represents the size of individual quarks within protons and neutrons, though quarks are considered point particles with no measurable size. Attometers are used in high-energy physics experiments that probe the internal structure of protons through deep inelastic scattering, revealing the distribution of quarks and gluons within.
