What is a Megameters (Mm)
Definition: A megameter (Mm) is a unit of length equal to one million meters (10^6 meters). It is used to measure large distances in both geography and astronomy.
History: The megameter was introduced alongside other metric units to standardize measurements of large distances. It has been mainly used in astronomical contexts to simplify expressions of distances in space.
Current Use: Megameters are used in astronomy to describe distances between astronomical objects such as the Earth and the Sun. They also appear in some applications in geology and planetary science.
What is a Parsecs (pc)
Definition: A Parsec (pc) is a standard unit of distance used in astronomy, equivalent to approximately 3.26 light-years or 30.86 trillion kilometers (19.17 trillion miles). It is commonly used to measure distances between stars and galaxies.
History: The term "parsec" originates from "parallax-second" and was first introduced in 1913 by British astronomer Herbert Hall Turner. It is defined as the distance at which one astronomical unit (AU) subtends an angle of one arcsecond. This method of measurement is fundamental in astrometry, helping astronomers determine stellar distances with high precision.
Current Use: Parsecs are widely used in astrophysics and cosmology to describe vast interstellar and intergalactic distances. They provide a more practical alternative to light-years when measuring astronomical scales, making them essential for celestial navigation, galaxy mapping, and space exploration.
