Halley's Comet had been seen every 76 years since at least 240 BC, and probably earlier than that. But most people didn't live 76 years, and the written records weren't exactly common back then. So few people noticed that there was a comet coming by every 76 years.
Edmund Halley DID make the connection, and analyzed the data of comet appearances in 1531, 1607 and 1682. In 1705, Halley said that these were all the SAME comet, and that the comet would return in 1758. It did (just barely!) and was named Halley's Comet in his honor.
In 1705 Halley determined the comet's periodicity, but he was not the first person to discover it.

Edmond Halley did not discover Halley's Comet. The comet was actually named after him because he was the first person to calculate its periodicity and predict its return in 1758. The comet has been observed for centuries before Halley made his calculations.
Edmond Halley had a comet called Halley's Comet named after him.

After Edmond Halley.
halley's comet was discovered in 1705 by Edmond halley
Halley's Comet is currently a little beyond the orbit of Neptune.
Edmund Halley did not invent anything, but he was a British astronomer known for calculating the orbit of the comet that now bears his name. Halley's Comet, which passes by Earth approximately every 75-76 years, was the first comet to be recognized as periodic.
The first "certain" appearance of Halley's Comet is from 240 BC, in the Chinese chronicle Records of the Grand Historian or Shiji, which describes a comet that appeared "in the east and moved north".
Edmond Halley. That is why it is named after him.
