Question

Which planet is smallest in size in the solar system?
A. Mercury
B. Venus
C. Mars
D. Saturn

Answer 1

Hint:It is named after the Greek god Hermes, the GOD of trade and messengers, mediator between gods and humans, and is translated into Latin Mercury.
It's a rocky body like the Earth, one of the four earthly planets in the solar system.
The center has higher iron content than any other large planet in the solar system, and this has been clarified by many hypotheses.

Complete answer:
Option A. Mercury
Mercury is the smallest planet in the Universe. For the longest time, Pluto was considered the smallest planet, but Pluto is no longer a planet, so we have returned to Mercury. Mercury tests an Ecuador of 4879 km.
Mercury is the smallest planet in the universe. Hence, this option is correct.
Option B. Venus
The second Sun planet is Venus. Venus. The Roman divinity of love and beauty is its name. Venus can cast shadows as the second brightest natural object in Earth's night sky after the moon and on rare occasions, can be visible in a huge, naked light.
Venus is the second planet from the sun. While being far away from the Sun, Venus is hotter than Mercury. Hence, this option is incorrect.
Option C. Mars
Mars is the Sun's fourth and Solar System's second-smallest planet, larger than Mercury alone. In English, Mars is called ``Red Planet" and is called the name of the Roman god of war.
Mars, 4th in order of distance to the Sun and 7th in scale and mass in the solar system. Hence, this option is incorrect.
Option D. Saturn
Saturn, after Jupiter, is the sixth largest planet in the solar system, and the second largest. It is a gas giant with about nine times the average radius of the earth. The Earth's average density is only one eighth, but Saturn is over 95 times more massive with its greater volume.
In the solar system, Saturn is the least dense planet. Hence, this option is incorrect.

Therefore, Mercury is smallest in size in the polar system. Hence, this option A. Mercury is the correct answer.

Note:Jupiter, the smallest of the Sun's planets, and Mercury and the world's biggest, provides a lot of insights into our solar system forming, our geochemical variability and Earth growth.
The solid silicate crust and coat tends to be Mercury, which has an iron sulfide outer core, a lower liquid core and a solid inner core. The Solar System is a rocky body like Earth and Mercury is one of four terrestrial planets.
