Sir Edmond Halley

Sir Edmond Halley (1656 – 1742) was an English astronomer who is best known for his study of comets, and the discovery that certain comets observed many years apart appeared to travel along similar orbits. In particular, he noticed that the comets of 1531, 1607, and 1682 seemed similar and he hypothesized that they were in fact the same comet. He predicted that the comet would return in 1758; when it was observed as predicted, the comet was named Halley’s Comet in his honor.

Halley’s Comet or Comet Halley , officially designated 1P/Halley, is a short-period comet visible from Earth every 75–76 years. Halley is the only known short-period comet that is clearly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime. Halley last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061

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.
