What is solar constant and its importance?

The dimension of solar constant is :

Which of the following is not a greenhouse gas?
 

Solar constant for earth is $2 \mathrm{cal} {\min }^{-1} {\mathrm{cm}}^2$, if distance of mercury from sun is $0.4$ times than distance of earth from sun then solar constant for mercury will be?

The greenhouse effect is due to

Each minute earth receives about $2 \mathrm{cal}$ of heat energy per square centimetre from the sun. This is called the solar constant $S$. The value of solar constant in $\mathrm{S}.\mathrm{I}$ units is
