Halley's Comet - Wikipedia
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.

Comet Halley moves backward (opposite to Earth's motion) around the Sun in a plane tilted 18 degrees to that of the Earth's orbit. Halley's backward, or retrograde, motion is unusual among short-period comets, as its greatest distance from the Sun (aphelion) is …

2024年10月17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. His calculations showed that comets observed in 1531, 1607, and 1682 had very similar orbits.

Halley’s Comet Facts - The Planets
Halley’s Comet is one of the most-awaited natural displays of our night sky. It is a short-period comet that approaches the inner Solar System every 75 years or so. The highly elliptical orbit of this comet brings it as far as the distance of Pluto. At its closest approach, it can be as close to the Sun between Mercury and Venus.

Halley's comet | What is, history, origin, characteristics
Halley's Comet, or 1P/Halley, is a large, high-gloss comet that orbits the Sun every 76 years. It is the best known short-haul kite in the Kuiper belt. It had its origins in the Oort Cloud and is believed to have been a long-haul comet in its early days.

Comets are made of ice, dust, and small particles of rock. They are solar system bodies that usually orbit the sun in highly eccentric orbits that could take them millions of years to complete. Comets that take less than 200 years to make the journey, like Halley’s, are called periodic.
Halley’s Comet – Introduction to Astronomy
Halley’s Comet was the first comet to be visited by spacecraft, in 1986; Vega 1 (USSR) and Giotto (European Space Agency). And, interestingly, it turns out that in the last 2,000 years the least-visible or poorest passage of Halley’s Comet to Earth was in 1986.
