Orbital property

Orbit semimajor axis is 45.0AU, but revolution orbit of 2010 KZ₃₉ is the orbit which is extremely almost a circle where the orbit eccentricity has only 0.06. On the other hand, the orbit angle of inclination declines with 26.12 degrees. I revolve for approximately 303 years, but know the perihelion passage time only at all roughly together on the last time, the next time [¹]. There is the document classifying in a キュビワノ group [³], but there is the document dividing into the classification called the separation heavenly bodies from the value of the big orbit angle of inclination [²]. In any case, it is thought that I do not do Neptune and the orbit resonance [²].

Physical property

The value of the absolute magnitude of 2010 KZ₃₉ is 4.0, and this is a big value next to 3.8 of 2010 EK₁₃₉ in the asteroid which an asteroid number is not given. The diameter becomes the huge heavenly bodies of 697km when I suppose albedo to be 0.09 [⁴]. This may become the resting hydraulic pressure equilibrium shape by mass of oneself and may meet the standard of the dwarf planet. By this thing, the candidate heavenly bodies of the dwarf planet include 2010 KZ₃₉ [⁶]. A value of the absolute magnitude is secondly big next to Sedna while it is thought that I am classified in the separation heavenly bodies [⁷]. In addition, under a condition of the same albedo, it is thought that the surface temperature reaches it from -231 degrees Celsius to -234 degrees Celsius [⁵]. The mass becomes 3.55*1,0²⁰ kg when I suppose mean density to be 2.0 g/cm³ applied to the Pluto type heavenly bodies.
