Best-fit convex shape model of (85990) 1999 JV6. The model was produced as a result of a pole search using light-curve data only, assuming a zero-YORP (constant period) solution, and has the pole located at λ = 55°, β = − 75°. Top row (leftto right): views along the Z, Y and X axes of the body-centric coordinate frame from the positive end of the axis. Bottom row (left to right): views along the Z, Y and X axes from their negative ends. For the model to be physically feasible under the assumption of principal-axis rotation, the Z-axis of the body (also the spin axis) should be aligned with the shortest axis of inertia. There is no relation between the longest axis of inertia and the X-axis of the body, instead the X-axis is arbitrarilyselected so that it would be in the plane of the sky at T₀. The units onthe X, Y, and Z axes are arbitrary, as the light-curve convex inversion model is not scaled in size.
