The Haversine formula enables us to calculate the distance between two points. $^{1}$ To convert right ascension given in hours, minutes and seconds and declination, given in degrees, minutes and seconds, to radians you do $$alpha = (RAh*15 + RAm/4 + RAs/240) imes pi/180$$ $$delta = (DEd pm DEm/60 pm DEs/3600) imes pi/180,$$ where in the latter formula you use plus signs for objects in the northern. You can cluster spatial latitude-longitude data with scikit-learn's DBSCAN without precomputing a distance matrix. The ‘(re)versed sine’ is 1−cosθ , and the ‘half-versed-sine’ is (1−cosθ)/2 or sin²(θ/2) as used above. To derive the law of haversines, one starts with the spherical law of cosines : cos ( c ) = cos ( a ). The Haversine formula is nice and fast, but it has a ‘fatal’ flaw of returning NULL sometimes when measuring the distance between a point and itself. In order to use this method, we need to have the co-ordinates of point A and point B. It is a special case of a more general formula in spherical trigonometry, the law of haversines, relating the sides and angles of spherical "triangles". R = 6,371km. Task.
