An astronomer measures the parallax angle of a distant star and determines it to be 0.599 arcseconds.?
How far away is the star in parsecs?
- RaymondLv 78 years agoFavorite Answer
Distance in parsec = 1 / parallax in seconds.
(parsec comes for PARallax SEConds; where seocnds means the parallax angle, in seconds of arc)
Distance to that star in parsecs = 1/0.599 = 1.67 parsecs (almost 5.5 light-years)

1/ 0.599 = 1.669 parsecs. As stars go, that's not very distant at all.

distance in parsecs = 1/(parallax in arc seconds)
You have this formula in your textbook or class notes.
