Question

The planet nearest to the Sun is ______.
A. Mercury
B. Venus
C. Mars
D. Earth

Answer 1

We will find out which one of the following planets takes less time to complete one revolution around the Sun because the planet which is nearest to the sun is our required answer.

Complete step by step answer:
The heavenly bodies that revolve around the Sun (nearest star), are called planets. All the planets have fixed paths called orbits on their own, through which it makes revolution. There are currently eight planets in our solar system which are named in sequence as: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The Sun is at the centre of the solar system. The gravitational force of attraction of the Sun keeps the solar system stable and the centripetal force of attraction makes the planets revolve.
Planets are divided into two groups: one is terrestrial planets and the another is giant planets. The terrestrial planets include Mercury, Venus, Earth and Mars, which contains hard surfaces primarily composed of rocks. On the other hand, Jupiter, Saturn, Uranus and Neptune are called gas giants, which are primarily composed of gases.
The planet which is closest to the Sun is Mercury, as it comes first in the sequence from the Sun. it completes one revolution around the Earth in just $88$ days, whereas the Earth takes $365$ days to make one complete revolution.

So, the correct answer is “Option A”.

Note:
In the solar system, the smallest planet is Mercury. The planet has a diameter of about $3030$ miles ($4876$ kilometres), making it around the size of the central United States and just marginally larger than the moon of Earth. Since Mercury is so small and so close to the sun, it is one of the five planets visible to the naked eye, that is the most enigmatic.
