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 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.
