Detailed explanation-1: -Astronomers have now linked the comet’s appearances to observations dating back more than 2, 000 years. Halley was last seen in Earth’s skies in 1986 and was met in space by an international fleet of spacecraft. It will return in 2061 on its regular 76-year journey around the Sun.
Detailed explanation-2: -Halley’s Comet is arguably the most famous comet in history. As a “periodic” comet, it returns to Earth’s vicinity about every 75 years, making it possible for a person to see it twice in their lifetime. It was last here in 1986, and it is projected to return in 2061.
Detailed explanation-3: -2023 is the year that Halley’s comet reaches its aphelion-it’s farthest point from the Sun-before making its return journey to loop around our star. Now in the southern hemisphere constellation of Hydra it will reach aphelion at 35.1 au (beyond the distance of the orbit of Neptune and closer to Pluto) in December 2023.
Detailed explanation-4: -Many comets are known to appear again and again after a definite period of time., one such is Halley’s comet which appears after every 76 years.
Detailed explanation-5: -Halley’s comet will next appear in the night sky in the year 2062. It orbits the sun every 75-76 years, so this is the time between appearances. Halley’s comet was recorded by Edmund Halley in 1682. It was seen again in 1758, 1835, 1910, and 1986.
