Based on predictions by Edmond Halley in 1705, Johann Georg Palitzsch observed a comet that was later named Halley's Comet .

Edmond Halley was an English astronomer, mathematician and physicist. He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720.

Johann Georg Palitzsch – 21 February 1788 in Prohlis) was a German astronomer who became famous for recovering Comet 1P/Halley on Christmas Day, 1758. The periodic nature of this comet had been deduced by its namesake Edmond Halley in 1705, but Halley had died before seeing if his prediction would come true.

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, appearing every 72–80 years, though with the majority of recorded apparitions occurring after 75–77 years. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley.
