On-sky projection map of the component orbits in the 47171 Lempo triple system, drawn to scale. Each grid square is 0.1 arcseconds wide and is fixed relative to the Lempo's periapsis represented as a red cross. North is up and East is left.
The large ellipse colored yellow represents the orbit of the outer component Paha, with its apsides drawn and labeled (Q=apoapse) and (q=periapse). The two smaller ellipses overlapping each other near the center represent the mutual orbits of Lempo and Hiisi, the two inner components that form the central binary. Lempo's smaller orbit is colored gray while Hiisi's orbit is colored white.
