Identify the least dense and most dense planets and provide an explanation as to why they are the least and most dense.

Explained

Explanation:

The most dense planet in  our solar system is Earth. Earth is most dense planet because

The least dense planet of the solar system is Saturn because Saturn is mostly made of gases and its size is smaller than the Jupiter. Jupiter has more gravity hence its density is higher to Saturn. Moreover, Uranus and Neptune are ice giants. Although they are also made of gases but due their distance from sun most of these gases have solidified. Hence making them more dense than Saturn and Jupiter.

that the claims meet official rules.

don't misinterpret the claims

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
