Question: What is the period of revolution on the planet where Haystack Catena is located, in Earth years?

full_context: Document 1: Planets in astrology: Mercury () is the ruling planet of Gemini and is exalted in Virgo and Aquarius. In classical Roman mythology, Mercury is the messenger of the gods, noted for his speed and swiftness. Echoing this, the scorching, airless world Mercury circles the Sun on the fastest orbit of any planet. Mercury takes only 88 days to orbit the Sun, spending about 7.33 days in each sign of the zodiac. Mercury is so close to the Sun that only a brief period exists after the Sun has set where it can be seen with the naked eye, before following the Sun beyond the horizon.Astrologically speaking, Mercury represents the principles of communication, mentality, thinking patterns, rationality and reasoning, and adaptability and variability. Mercury governs schooling and education, the immediate environment of neighbors, siblings and cousins, transport over short distances, messages and forms of communication such as post, email and telephone, newspapers, journalism and writing, information gathering skills and physical dexterity. The 1st-century poet Marcus Manilius described Mercury as an inconstant, vivacious and curious planet.
Document 2: Kuiper quadrangle: The Kuiper quadrangle, located in a heavily cratered region of Mercury, includes the young, 55-km-diameter crater Kuiper (11° S., 31.5° ), which has the highest albedo recorded on the planet, and the small crater Hun Kal (0.6° S., 20.0° ), which is the principal reference point for Mercurian longitude (Davies and Batson, 1975). Impact craters and basins, their numerous secondary craters, and heavily to lightly cratered plains are the characteristic landforms of the region. At least six multiringed basins ranging from 150 km to 440 km in diameter are present. Inasmuch as multiringed basins occur widely on that part of Mercury photographed by "Mariner 10", as well as on the Moon and Mars, they offer a potentially valuable basis for comparison between these planetary bodies.
Document 3: Artynia Catena: Artynia Catena is a feature in the Arcadia quadrangle of Mars, located at . It is long and was named after a classical albedo feature at The term "Catena" refers to a chain of craters.
Document 4: Haystack Catena: Haystack Catena (Haystack Vallis until March 2013) is a catena at 4.7° N, 46.2° W on Mercury. It superficially resembles a graben but is a chain of overlapping secondary craters. It was named after Haystack Observatory.
Document 5: Michelangelo quadrangle: The Michelangelo quadrangle is in the southern hemisphere of the planet Mercury, where the imaged part is heavily cratered terrain that has been strongly influenced by the presence of multiring basins. At least four such basins, now nearly obliterated, have largely controlled the distribution of plains materials and structural trends in the map area. Many craters, interpreted to be of impact origin, display a spectrum of modification styles and degradation states. The interaction between basins, craters, and plains in this quadrangle provides important clues to geologic processes that have formed the morphology of the mercurian surface.
Document 6: Neptune: Neptune is the eighth and farthest known planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Among the giant planets in the Solar System, Neptune is the most dense. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune.[c] Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50×109 km). Named after the Roman god of the sea, its astronomical symbol is ♆, a stylised version of the god Neptune's trident.
Document 7: Dorsa Harker: Dorsa Harker is a wrinkle ridge at in Mare Crisium on the Moon. It is 213 km long and was named after Alfred Harker, an English petrologist, in 1976.
Document 8: Neptune: Neptune is the eighth and farthest known planet from the Sun in the Solar System. In the Solar System, it is the fourth - largest planet by diameter, the third-most - massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth and is slightly more massive than its near - twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50 × 10 km). It is named after the Roman god of the sea and has the astronomical symbol ♆, a stylised version of the god Neptune's trident.
Document 9: Neptune: Neptune is the eighth and farthest known planet from the Sun in the Solar System. In the Solar System, it is the fourth - largest planet by diameter, the third-most - massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth and is slightly more massive than its near - twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 AU (4.5 billion km). It is named after the Roman god of the sea and has the astronomical symbol ♆, a stylised version of the god Neptune's trident.
Document 10: Haystacks (Lake District): Haystacks, or Hay Stacks, is a hill in England's Lake District, situated at the south-eastern end of the Buttermere Valley. Although not of any great elevation (597 m, 1,958 ft), Haystacks has become one of the most popular fells in the area. This fame is partly due to the writings of Alfred Wainwright, who espoused its attractions and chose it as the place where he wanted his ashes scattered. Its summit is interesting and contains a number of attractive rock formations and tarns.
Document 11: Goldstone Catena: Goldstone Catena (Goldstone Vallis until March 2013) is a catena on Mercury located at 15.8 S, 31.7 W. It is named after Goldstone Observatory. While it superficially resembles a graben, it is a chain of overlapping secondary craters.
Document 12: Mercury (planet): Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 88 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger to the gods.
Document 13: Pantheon Fossae: The Pantheon Fossae are a radial set of troughs in a region in the middle of Caloris Basin on Mercury. They appear to be a set of graben formed by extensional faults, with a 40 km crater located near the center of the pattern. The exact origin of this pattern of troughs is not currently known. The feature was nicknamed "the Spider" before receiving its official name.
Document 14: Sobkou Planitia: Sobkou Planitia is a large basin on the planet Mercury. It is named after the ancient Egyptian messenger deity Sobkou (whose name is more usually transliterated Sobek). He was associated by the Egyptians with the planet Mercury.
Document 15: Mars: Mars is the fourth planet from the Sun and the second - smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the ``Red Planet ''because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
