WebSep 16, 2024 · Halley's backward, or retrograde, motion is unusual among short-period comets, as its greatest distance from the Sun (aphelion) is beyond the orbit of Neptune. Halley's orbit period is, on average, 76 Earth years. This corresponds to an orbital circumference around the Sun of about 7.6 billion miles (12.2 billion kilometers). WebInterplanetary Seasons. Every planet in the solar system has seasons. Most have four like the Earth -- called Winter, Spring, Summer and Fall -- but that's where the similarities end. Extraterrestrial seasons are hardly noticeable on some planets (Venus), mindbogglingly extreme on others (Uranus) and in some cases simply impossible to define ...
