Light Years

Light year is the distance that light travels in one year in the vacuum of space. It is equivalent to about 9.46 trillion kilometers or 5.88 trillion miles. Light year is used as a unit of measurement to describe the vast distances between celestial objects in the universe. It is commonly used in space and astronautical engineering to calculate the distance between planets, stars, and galaxies. The concept of light year is important in understanding the scale of the universe and the vastness of space. It is also used in the design and navigation of spacecraft that travel long distances in space.
