What is Light year ?
A Light year is a unit of distance used in astronomy to measure vast distances across the universe. It represents the distance that light travels in one year through the vacuum of space, at a speed of approximately 299,792 kilometers per second (about 186,282 miles per second).
To put it into perspective, one light year is equivalent to about 9.46 trillion kilometers (or about 5.88 trillion miles). This unit is incredibly useful for describing distances between stars, galaxies, and other celestial objects that are beyond our solar system.
In simpler terms, when we say a star is located 10 light years away, it means that the light we see from that star today actually started its journey 10 years ago. Light years help astronomers understand the immense scale of the universe and how long it takes for light, the fastest known thing, to travel across these vast cosmic distances.
Understanding light years is essential for studying the universe's structure, its evolution over time, and our place within it. It allows scientists to explore and interpret the observations made by telescopes and spacecraft as they probe deeper into the mysteries of outer space.
What is Millimeter ?
A Millimeter is a unit of length in the metric system, used to measure very small distances. It is abbreviated as "mm". One millimeter is equal to one thousandth of a meter, which means there are 1,000 millimeters in a meter.
To give you a sense of scale, a millimeter is about the width of a paperclip or the thickness of a dime. It's much smaller than a centimeter, which is roughly the width of a small button. Millimeters are commonly used in fields where precision is important, such as engineering, manufacturing, and science, to measure things like the thickness of materials, the diameter of small objects, or the spacing between components.
