Ammonia planet

Ammonia planet is an assumed class of planet with surface covered in lakes or oceans of with ammonia clouds in the.

Appearance
Viewed from space, ammonia oceans would usually appear dark brown due to large amounts of s dissolved in it. Although ammonia oceans would appear blue in absent or small amounts of alkali earth metals dissolved in it. The lands appear blackish due to black vegetation.

Atmosphere and climate
Ammonia planets tend to have similar s to Earth's, except it uses ammonia as a "variable gas" instead of as it is on Earth. For example, there are ammonia rain or ammonia snow instead of water rain or water snow. Those planets tend to be very cold, at around −150°F (−115°C), or warmer depending on the thickness of the atmosphere. Their atmospheres tend to be composed mostly of (N$2$) and  (O$2$ with variable amounts of ammonia (NH$3$) and trace amounts of  (CO$2$) and other gases.

Life
The -bearing status on ammonia planets are fair. Life on ammonia planets are strange that they can adapt to extreme cold and use ammonia as a, whereas life on Earth use water as a solvent. Some of the plants on ammonia planet use using light from the parent star while others perform. It is predicted that plants use ammonia (NH$3$) and (CO$2$) to produce  (CH$3$NH$2$), nitrogen (N$2$), and oxygen (O$2$) using the balanced equation below:


 * 10 NH$3$ + 3 CO$2$ + energy → 6 CH$3$NH$2$ + 4 N$2$ + 3 O$2$.

It is also predicted that animals inhale oxygen and exhale carbon dioxide for, just like animals here on Earth. Animals also eat foods rich in s and drink liquid ammonia. The main on ammonia planets is the  compared to the  here on Earth.

However, life on some ammonia planets may not be, but as they have better survivability to extreme cold than carbon-based life.

Abundance
There are an estimated 24 billion ammonia planets in alone, more than half as abundant as methane planets. They make up 4.6% of all 524 billion terrestrial planets and 2.9% of all 820 billion planets in our galaxy.
