The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years or 206,000 astronomical units (au), i.e. One parsec is defined as the distance between the line drawn from the centre of the Earth and the Sun making an angle of 1 second with each other. Parallactic second or parsec is a unit of large distances used by the astronomers to measure large distances outside our solar system. 1 parsec is the distance which creates a parallax angle of 1 second at the earth. ![]() 1 AU is roughly equal to the distance between the sun and the earth. The unit parsec is much bigger than AU(astronomical unit). Of the three units, the kilogram is the largest and the milligram is the smallest. The most commonly used units of mass are kilogram, gram, and milligram. When we use 60x magnification, we boost a bright 1″ object to appear an arcminute wide, bringing it to the threshold of resolution. The arcsecond lies deep within the telescopic realm. It is the apparent size of a dime seen from 2½ miles (4km) away. An arcsecond, which we use a lot in astronomy, is a truly tiny angle.
