Why uranus is called green planet?

Uranus appears green-blue due to its atmospheric composition:Scientific explanation:- Methane gas in Uranus's atmosphere absorbs red light from sunlight- Reflects blue and green wavelengths back into space- This selective absorption creates the cyan/green appearanceAtmospheric composition:- 83% hydrogen- 15% helium - 2% methane (responsible for the color)- Trace amounts of other gasesAdditional factors:- Distance from Sun - receives faint sunlight, enhancing color perception- Lack of surface features - uniform color appearance- Ice giant composition - different from gas giants like JupiterThe methane acts like a filter, removing red components from reflected sunlight, making Uranus appear greenish-blue to our eyes. This is similar to why Neptune appears blue, though Neptune's deeper blue suggests additional unknown atmospheric components.

Uranus is often called the greenish-blue planet because of the presence of methane gas in its atmosphere, which absorbs red light and reflects blue-green wavelengths. Its bluish-green hue is visible even in telescopic observations from Earth.
