Halley's Comet Embarks on Return Journey to Earth

Halley's Comet is reaching its farthest point from the sun, known as its aphelion, at a distance of about 35 astronomical units (AU). This marks the midway point of its 76-year orbit around the sun. After spending the last 38 years moving away from Earth, the comet will now spend the next 38 years moving closer. Halley's Comet was the first comet predicted to return to Earth's skies, and it will make its next close approach to the sun in 2061. In the meantime, two meteor showers associated with debris from the comet can be observed twice a year.
