In the case of need to calculate the solar constant on Mars, the formula would be: SC = L⊙ 4π ⋅ r2, (3) where the constant L⊙ is the solar luminosity of 3.828 × 10 26 W and r is the distance of Mars from the Sun, which is 2.2794 × 10 11 m. The solar constant on Mars would therefore be 586 W/m 2 [ 67, 68 ].
