The concept of the position angle is inherited from nautical navigation on the oceans, where the optimum compass course is the course from a known position s to a target position t with minimum effort. Setting aside the influence of winds and ocean currents, the optimum course is the course of smallest distance between the two positions on the ...

Barnard's Star, showing position every 5 years 1985–2005. Barnard's Star has the largest proper motion of all stars, moving at 10.3″ yr −1. Large proper motion usually strongly indicates an object is close to the Sun. This is so for Barnard's Star, about 6 light-years away. After the Sun and the Alpha Centauri system, it is the nearest ...
In spherical astronomy, the parallactic angle is the angle between the great circle through a celestial object and the zenith, and the hour circle of the object. [1] It is usually denoted q . In the triangle zenith—object—celestial pole, the parallactic angle will be the position angle of the zenith at the celestial object.
The Perfect Couple, a 2018 thriller by Elin Hilderbrand, is having quite the moment right now. In case you haven't read the book (or watched the smash-hit, Nicole Kidman-starring series), here's th
