If Star 1 emits more electromagnetic radiation per unit area per unit time than Star 2, we can conclude that: the stars may have the same temperatures, depending on their chemical compositions. Star 1 is at a higher temperature. Star 2 is at a higher temperature. the stars may have the same temperatures, depending on their relative sizes. It was found that the amount of radiation emitted by Surface 1 of the thermal radiation cube is greater than that emitted...

Suppose your planet at 1 meter from the ball represents a distance of 4 x 10^7 km from the star. The next closest star to the Sun is 4 x 10^13 km away. How far away from the model star would you have to be for the distances in the system to be to scale? Express your answer in meters and kilometers. From the correctly scaled distance, could we actually see the planet as it moves in front of the...
