Light Year

A light year is a unit of distance used in astronomy to measure how far light travels in one year. Light moves extremely fast—about 299,792 kilometers per second—so in one year, it travels roughly 9.46 trillion kilometers (or about 5.88 trillion miles). Light years help scientists express the huge distances between stars and galaxies. For example, the nearest star to Earth, Proxima Centauri, is about 4.24 light years away. The term “light year” can be confusing because it sounds like a measure of time, but it actually measures distance.

Micrometer

A micrometer (µm), also called a micron, is an extremely small unit of length in the metric system. It is equal to one-millionth of a meter (0.000001 meters). Micrometers are used to measure tiny objects that are invisible to the naked eye, such as bacteria, cells, or the thickness of a human hair (which is about 50 to 70 micrometers thick). The symbol for micrometer is "µm". This unit is very important in science, engineering, and manufacturing where precise measurements are needed at microscopic scales. Because it is so small, the micrometer helps scientists study the details of very small structures.
