For semi-major axis a, orbital period T and eccentricity e, the average orbital speed is given by:

{\begin{aligned}v_{o}&={\frac {2\pi a}{T}}\left[1-{\frac {e^{2}}{4}}-{\frac {3e^{4}}{64}}-\dots \right]\\&=18.31\ {\mbox{km/s}}\left[1-0.0177-0.00008-\cdots \right]\\&\approx 17.98\ {\mbox{km/s}}\\\end{aligned}}\!\,

For the circumference of an ellipse, see: H. St̀eocker; J. Harris (1998). Handbook of Mathematics and Computational Science

. Springer. pp. 386. ISBN 0-387-94746-9.

For asteroid albedo α, semimajor axis a, solar luminosity $L_{0}$ , Stefan–Boltzmann constant σ and the asteroid's infrared emissivity ε (≈ 0.9), the approximate mean temperature T is given by:

{\begin{aligned}T&=\left({\frac {(1-\alpha )L_{0}}{\epsilon \sigma 16\pi a^{2}}}\right)^{\frac {1}{4}}\\&=\left({\frac {(1-0.0436)(3.827\times 10^{26}\ {\mbox{W}})}{0.9(5.670\times 10^{-8}\ {\mbox{W/m}}^{2}{\mbox{K}}^{4})16\cdot 3.142(3.959\times 10^{11}\ {\mbox{m}})^{2}}}\right)^{\frac {1}{4}}\\&=173.7\ {\mbox{K}}\end{aligned}}
