The phrase "year orbit" refers to the path or journey that a planet takes around the sun in one complete cycle, which takes around 365 days to complete. Full definition
More precise observations should become possible as their 80 - year orbit carries them farther apart. (sciencemag.org)
VP113, however, is currently located around 83 AUs from our Sun, Sol — an orbital distance that is close to three times farther out than that of Pluto or Neptune, and it will eventually move more than five times farther away (around 452 AUs) in a 4,590 - year orbit around Sol; it's orbital semi-major axis is around 276 AUs with an extremely high eccentricity of 0.710 (more on VP113's orbit from astronomer Scott S. Sheppard. (solstation.com)
Typically a few kilometers in diameter, comets orbit the Sun in paths that either allow them to pass by the Sun only once or that repeatedly bring them through the solar system (as in the 76 - year orbit of Halley's Comet). (webbtelescope.org)
