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 Kilometers
A kilometer (km) is 1,000 meters and the standard unit for measuring longer distances in most of the world. It takes about 10-12 minutes to walk one kilometer at a normal pace. Common references include: a typical city block might be 100-200 meters (0.1-0.2 km), most cars display speed in km/h, and marathon races are 42.195 kilometers long. Road signs, GPS systems, and maps globally use kilometers to indicate distances between cities and locations.
