The light from star 1 reaches star 3 in 138 years and star 2 in 63 years. which of these conclusions about the stars is correct? a. the distance between star 2 and star 3 is 75 light years. b. the distance between star 2 and star 3 is 201 light years. c. star 2 is 138 miles away from star 3. d. star 2 is 63 kilometers away from star 3.

The correct answer is A

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
