The Solar Constant refers to how much energy Earth gets from the Sun, per square meter (or another convenient unit of area). It is approximately 1.3-1.4 kW/m2 at the top of the atmosphere; the amount that reaches the surface is perhaps 2/3 of that value under ideal conditions - for example, no clouds.
its fairly constant,increasing only 0.2% at the peak of each 11 year solar cycle.

The solar constant is the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere in a plane perpendicular to the rays. See link for formula

The solar constant of Mercury varies as the intensity of the sun changes. This rate of variation is greater than on earth. However, the mean solar constant for Mercury is 9130 W/m^2 or 9.13 kW/m^2.
NO, all hings were not travel at constant things but some things r travel in constant speed for example solar system

Solar Constant
It ranges from 1.361 kilowatts per square meter at solar minimum to approx 1.362 kW/m^2 at solar maximum
Sunlight isn't constant. There's no sun at night.
These are called renewable sources, though they are not necessarily constant. You can include wind, solar, wave, tidal, hydro, and biomass.
