Edmond Halley was an English mathematician and astronomer (November 8, 1656 – January 14, 1742
In 1678 he published a list of 360 stars in the southern celestial hemisphere, the position of which he observed during his service in St. Helena, and the passing of Mercury before the disk of the Sun in 1677. Halley is the first who discoveres that stars do not remain constantly in their position and that each of them has its own movement, confirming those of Sirius and Arcturus.
