Neptune's Thermal Environment

extracted from Thermal Environments JPL D-8160

The following table summarizes the range of Direct Solar, Reflected Solar (Albedo), and Planetary Infrared for the planet Neptune.


                 Perihelion       Aphelion         Mean

----------------------------------------------------------------

Direct Solar      1.54 W/sqM      1.49 W/sqM       1.51 W/sqM

Albedo             0.282           0.282            0.282
(subsolar peak)

Planetary IR.     0.52 W/sqM      0.52 W/sqM       0.52 W/sqM

The planet Neptune has a fairly high albedo. Its thermal environment are so low that it could almost be ignored except for very sensitive instruments and detectors.
