The term “Green Planet” is not commonly used as a nickname for any planet in our solar system. Planetary nicknames are typically associated with specific characteristics or features of the planet, such as the “Red Planet” for Mars due to its reddish appearance, or the “Gas Giant” for Jupiter and Saturn because of their predominantly gaseous compositions.

Earth is sometimes referred to as the “Blue Planet” because of its abundant surface water, which gives it a blue appearance when viewed from space. However, the term “Green Planet” is not a widely recognized nickname for any planet in our solar system.
