Relationship between arcseconds in parsecs

Lecture 6: How Far is a Star?

relationship between arcseconds in parsecs

Your location changes by 2 AU between these times. Therefore The parsec is defined as the distance at which a star has a parallax of 1 arcsecond. In other The star Proxima Centauri has a parallax p = arcsecond. There is an inverse relation between star's parallax and its distance. A star which has a parallax 1 arcseconds is at a distance of 1 parsec. the distance to a star in parsecs, divide 1 by the arcseconds of parallax. which you measure as the angle between the Earth's position now.
