Question

Jupiter and Saturn, despite being considerably farther from us than the inner terrestrial planets,are very bright in our sky.Which of the following choices are possible explanations for this?
Choose one or more:
A. They are more reflective (higher albedo) than most of the terrestrial planets.
B. They are so hot that they emit blackbody radiation that peaks in the visible.
C. They are larger than the terrestrial planets.
D. Dust obscures our view of the inner planets more than the outer ones
E. Since they are closer to stars, more starlight is reflected off of them than the inner planets.

Answer 1

Answer:

The good answers here are:

A. They are more reflective (higher albedo) than most of the terrestrial planets.

C. They are larger than the terrestrial planets.

Explanation:

Light colored clouds found there have a better, reflective albedo. And both planets are so much bigger than Earth, they´re the biggest planets of our solar system.  These are some factors of their brightness in our sky.
