The temperature on Ceres has been calculates as 167 K (-106.15 Celsius) at the average distance from the sun (Semi-major axis) and 239 K (-34.15 Celsius) at the closest distance from the sun (Perihelion).

Unofficially,

Distance ... ... Irradiance (W/m^2) ... ... % of Earth's... ... Temperature

Minimum: .............210.91 ........................ 15.41% ................239 K

Average: ............. 178.51.........................13.06% ................137 K

Maximum: ............. 153.23.........................12.217%.................??

I would then give a rough linear extrapolation for the minimum as 61 K (-212 °C) base on difference between ratios.

((((695500000)^2)*(0.0000000567051)*((5778)^4))/((446669320000)^2)) equals 153.23
