What is Parsec ?
A Parsec is a unit of length used in astronomy to measure vast distances between celestial objects like stars and galaxies. It stands for "parallax arcsecond," which relates to the apparent shift or angle when viewing a star from different points in Earth's orbit.
Specifically, one parsec equals about 3.26 light-years, or approximately 30.857 trillion kilometers (19.173 trillion miles). This unit is especially useful for describing distances beyond our solar system, where the distances involved are immense.
To understand it better, imagine trying to measure the distance to a star from Earth. A parsec helps astronomers calculate this by considering the slight shift in the star's position as seen from Earth during its orbit around the Sun. It's a fundamental tool in astronomy for understanding the vast scale of the universe and mapping the positions of celestial objects across the cosmos.
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.
