D. Mercury, Venus, earth, mars, Jupiter, Saturn, Uranus, Neptune.

Answer 1

Hint: Before attempting this question, one should have prior knowledge about the solar system and also remember that the closest planet to the sun comes first in the correct order, using this information to approach the solution of the question.

Complete step by step answer:
Mercury is the first planet of our solar system that is closer to the sun. Thus, it is the first planet in which different rays of sun can reach easily. Its size is smaller as compared to other planets. It is the hottest planet due to its closeness to the sun. Venus is in the second position from the sun. It is similar to earth in shape and size and mostly is described as earth’s sister or “twin”. Venus is the hottest planet of our solar system even in comparison to mercury because of its close proximity to the sun and the dense atmosphere. The third planet earth is the till called the blue planet where life exits. Earth has water and an atmosphere, meaning it has an ozone layer that protects it from harmful rays of sun. Earth's size is the fifth largest planet in our solar system. Mars is the fourth planet from the sun. it is the second smallest planet after mercury. It is often referred to as a red planet. Atmosphere of mars is mainly composed of carbon dioxide, nitrogen, and argon. Jupiter is the fifth planet from the sun and it is the largest among all the planets. Jupiter is called a gas giant planet as it mainly consists of hydrogen, helium gas, similar to the sun. Saturn is the sixth planet from the sun. It is the second largest planet after Jupiter. Saturn is a flattened ball. Saturn has 62 moons. Uranus is the seventh planet from the sun. it is the third largest planet after Jupiter and Saturn. The Uranus atmosphere is mostly hydrogen and helium with a small amount of methane and ammonia. The methane gives Uranus its blue color. Neptune is the eighth planet from the sun. It is the fourth largest planet by diameter. It is the densest giant planet. It is made up of hydrogen, helium and methane. Therefore, we can conclude the order of planets in relation to the solar system is mercury, Venus, earth, mars, Jupiter, Saturn, Uranus, Neptune.

So, the correct answer is “Option D”.

Note:
A planet is said to be a planet due to mainly three things that it must do:
(I)It must orbit around a star.
(II)It must be big enough to have its own gravity clear away any other objects of a similar size near its orbit around the sun.
(III)It must be big enough to have its own gravity to force it into a spherical shape.
