Final answer:
If astronomers lived on Venus instead of Earth, solar constant measurements would be lower due to the closer proximity of Venus to the Sun.
Step-by-step explanation:
The solar constant is the amount of solar electromagnetic radiation received at the outer atmosphere of a planet.
If astronomers lived on Venus instead of Earth, the solar constant measurements would be lower due to the closer proximity of Venus to the Sun.
Venus is about 30% closer to the Sun than Earth, so it receives more solar radiation. However, the thick atmosphere of Venus causes a significant amount of the radiation to be absorbed and reflected back into space, resulting in a decrease in the solar constant compared to Earth.
