Triple

Target class: hypothesized comet reservoir
Context triple: [Hills cloud, instanceOf, hypothesized comet reservoir]

• A. reservoir of small Solar System bodies
  A reservoir of small Solar System bodies is a dynamically stable region of space, such as the Kuiper Belt or Oort Cloud, that gravitationally stores large populations of minor objects like comets, asteroids, and icy planetesimals over long timescales.
• B. Jupiter-family comet
  A Jupiter-family comet is a short-period comet whose orbit is strongly influenced by Jupiter, typically with an orbital period of less than 20 years and low inclination relative to the ecliptic plane.
• C. comet reservoir chosen
  A comet reservoir is a vast, distant region of space surrounding a star system where countless icy bodies and cometary nuclei are gravitationally stored and occasionally perturbed inward to become observable comets.
• D. scattered disc object candidate
  A scattered disc object candidate is a distant icy body in the outer Solar System whose highly eccentric and inclined orbit suggests it may belong to the scattered disc population but lacks sufficient observational data for definitive classification.
• E. possible dwarf planet
  A possible dwarf planet is a celestial body that is suspected to meet the criteria for dwarf planet status—orbiting the Sun, being nearly round in shape, and not having cleared its orbital neighborhood—but has not yet been officially classified as such.
• F. None of above.
