Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [16] appearing every 72–80 years, [17] though with the majority of recorded apparations (25 of 30) 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.

2024年12月10日 · Halley’s Comet, the first comet whose return was predicted and, almost three centuries later, the first to be imaged up close by interplanetary spacecraft. In 1705 English astronomer Edmond Halley published the first catalog of the orbits of 24 comets.

He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720. From an observatory he constructed on Saint Helena in 1676–77, Halley catalogued the southern celestial hemisphere and recorded a transit of Mercury across the Sun.

Halley is often called the most famous comet because it marked the first time astronomers understood comets could be repeat visitors to our night skies. Astronomers have now linked the comet's appearances to observations dating back more than 2,000 years.

2016年11月8日 · The famous comet named for astronomer Edmond Halley only passes by the Earth roughly once every 76 years, but it’s appearances have often played a surprising role in historical events.

2024年11月3日 · Halley is often called the most famous comet because it marked the first time astronomers understood comets could be repeat visitors to our night skies. Astronomers have now linked the comet’s appearances to observations dating back more than 2,000 years.

2024年9月17日 · Halley’s Comet is the only known short-period comet that is consistently visible to the naked eye, as well as the only short-period comet that can appear twice in a human lifetime. And during the comet’s last approach in 1986, it become the first comet in history to be studied in detail by spacecraft.

2025年1月10日 · Edmond Halley was an English astronomer and mathematician who was the first to calculate the orbit of a comet later named after him. He is also noted for his role in the publication of Isaac Newton’s Philosophiae Naturalis Principia Mathematica.

2025年1月10日 · Though wide-ranging in his interests, Halley displayed a high degree of professional competence that foreshadowed scientific specialization. His wise assessment of Newton’s work and his persistence in guiding it to completion earned for him an important place in the emergence of Western thought.
