20 Parsec = 1.7394525965311E+16 Roman actus
Parsec to Meter | Parsec to Foot | Parsec to Centimeter | Parsec to Inch | Parsec to Kilometer | Parsec to Mile | Parsec to Millimeter | Parsec to Yard | Parsec to Micrometer |20 Parsec equal 1.7394525965311E+16 Roman actus.
Every 1 Parsec = 8.6972629826554E+14 Roman actus and so, 20 Parsec = 20 multiplied by 8.6972629826554E+14 = 1.7394525965311E+16 Roman actus.
What is "parsec"?
In the space scale, distances can't be expressed by meters or feet. Professional astronomers use the parsec unit to express these incredible distances. The parsec is a unit for expressing distances between stars and galaxies. One parsec equals 3.26 light-years, which is equivalent to 3.09 × 1013 km.
Parsec has a special way to measure distance, it depends on trigonometry. It is defined as the distance at which one astronomical unit subtends an angle of one arcsecond.
The parsec distance of an object is the reciprocal of its parallax in seconds of arc.
It is amazing to know that when we look at the night sky, we can see stars which are nearly a distance of 500 parsecs of the Sun.
There is a star is called Proxima Centauri. It exists within another solar system called Alpha Centauri triple-star system. It has a parallax of 0.769 second of arc which means it is 1.30 parsec far from us.
