Type 1: Breathable to Humans
*Planets with this type of environment contain appropriate levels of oxygen, nitrogen and other gases just like on Earth that require no breath masks or environment suits. Planets with this type of environment mostly support some forms of indigenous life. Earth-like planets above 90% chance for human habitation usually fall into this type.

Type 2: Breath Mask Suggested
*Planets with this type of environment contain appropriate levels of oxygen and nitrogen, however, due to lack or the presence of contaminants and/or other trace of gases, these atmospheres usually caused detrimental effects to humans over a shorter period of time. Because of this, a breath mask is suggested but requires no environment suits. Planets with this type of environment usually support some forms of indigenous life. Planets such as Earth-like worlds or forest types usually fall into this category.

Type 3: Breath Mask Required
*Planets with this type of environment lack or contain too many levels of oxygen, nitrogen or other trace of gases that are harmful to humans. Such examples of these include the presence of high levels of carbon dioxide, neon, xenon, ammonia, or other gases that cannot be found on Earth's atmosphere. Because of this, wearing a breath mask is an necessity but requires no environment suits. Planets with this type of environment could support some forms of indigenous life that have adapted to the atmosphere and environment billions of years ago due to evolution. Exotic planets such as swamps, jungles, or other forest worlds usually fall into this category.

Type 4: Environment Suit Required
*Planets with this type of environment are either toxic, flammable, has too thin or no atmosphere at all. These types of atmospheres can cause immediate incapacitation or death in humans when exposed to air. However, this is not always the case. This type could also have an atmosphere such as Type 3, but with a hostile environment that could lead serious suffering on the human body. Such examples of these environments are severe weather conditions, freezing or scorching temperatures, or exposure of skin on the surface. Planets with this type rarely support life due to the harsh environment. Planets such as barren, deserts, ice and oceanic worlds usually fall into this category.

Type 5: Unable for Human Exploration
*Planets with this type of environment are not suited for human exploration due to its immense surface pressure that could immediately crush spacecrafts when landing on the surface, extreme weather conditions, searing temperatures that could melt any man-made objects, or has no surface to land on (gaseous or deep-ocean planets with immense pressures). Planets with this type of environment have a very low chance of supporting indigenous life. Planets such as gas giants, deep-oceans with extreme pressures, volcanic worlds and any other hostile surfaces usually fall into this category.
