Question

The Greek word which is the origin of the word 'planets' means ___.

Answer 1

Hint: Planet refers to any of the nine large celestial bodies present in the solar system that is constantly revolving around the sun and shine by reflected light; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto are the 9 planets, in order of their proximity to the sun. All the nine planets rotate around the sun in a counterclockwise direction.

Step by step solution: Our word "planet" is derived from the Greek word planetes, meaning "wanderer." The word planet in general means ‘wanderer’. This is because the planets do appear to wander listlessly across the night sky. The stars also move across the sky in the direction of east to west but at the same time they are relative to each other, they always look fixed. The planets, on the other hand, seem to move relative to the fixed stars in the backward and forwards directions. This is why they are referred to as the same.
Planets do not possess any light of their own but are reflecting the light of the sun. Planets also do not twinkle like the stars because they are much closer to us. The earth is also a planet and is the only place we know in the universe which can promote a happy life.

Additional information: As of now, there are eight planets in the solar system and not 9.
The eight planets present in the solar system are as follows:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Note: According to the Greeks and the other earliest astronomers, this group consisted of the five planets visible to the naked eye and excluded Earth. But truly, the term planet was used only for those five objects, the term was later broadened, especially in the Middle Ages, to add the Sun and the Moon, sometimes signifying to "Lights", making a sum of seven planets. Astrologers retain this definition even today.
