Constellations – Separate parts of the starry sky, which were conditionally divided in ancient times, became known as constellations. There are modern boundaries that divide the celestial sphere into 88 constellations. They were established in 1922-1935 by the International Astronomical Union. These boundaries pass only through the intersection points of the equatorial coordinates and the declination circles of the coordinate system of the epoch of 1875.
