 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Saturn is 9.5 astronomical units (AU) from the Sun, while Mars is only 1.5 AU from the Sun. Saturn is also larger than Mars. Based on this information, how does the average surface temperature on Mars compare to the average surface temperature of Saturn?
 A Since Mars is closer to the Sun than Saturn, it has a higher average surface temperature B Saturn is larger than Mars and absorbs more light, so it has a higher average surface temperature. C Since both planets are more than 1 AU from the Sun, their average surface temperatures are equal. D Even though Saturn is farther away, Saturn’s rings cause it to have a lower average surface temperature.
Explanation:

Detailed explanation-1: -Saturn is also much larger than Mars. Based on this information, how does the average surface temperature on Mars compared to the average surface temperature on Saturn? Since Mars is closer to the Sun than Saturn, it has a higher average surface temperature.

Detailed explanation-2: -At a distance from the Sun that is 9.5 times as far as Earth’s, Saturn takes approximately 29.5 Earth years to make one solar revolution. The Italian astronomer Galileo in 1610 was the first to observe Saturn with a telescope.
