Question

Suppose a scientist identifies a rocky planet with a thin atmosphere in a different solar system. Based on the characteristics of planets in our solar system, what might the scientist predict?
A. Like Neptune, the planet has a layer of methane gas


. B. The planet is likely to have

many moons

.

C. The planet is close to its sun the way Mercury is close to the sun in our solar system


D. A year on the planet is likely to be many times longer than a year on Earth.

Answer 1

Answer: The correct option is C.

The planet is close to its sun the way Mercury is close to the sun in our solar system.

Explanation:

Solar system consists of the Sun and the eight planets, dozens of moons, asteroids,comets, meteoroids. The names of the eight planets includes:

-- Mercury

-- Venus

-- Earth

-- Mars

-- Jupiter

-- Saturn

-- Uranus and

-- Neptune.

Mercury is a rocky planet with a thin atmosphere. It is the smallest terrestrial planet and the closest to the sun. It is said to have a thin atmosphere because it lacks hydrogen. The atmosphere gets thinner as one moves further away from the planets surface.

Mercury is a rocky dense planet because its composed mainly of iron and nickel with an iron core. It is also covered by a thin layer of tiny particle silicates.

Therefore the rocky planet with a thin atmosphere identified by the scientist must be a planet that is close to its sun the way Mercury is close to the sun in our solar system.
