Anaera has a thin atmosphere of carbon dioxide and nitrogen, and though it is classified as a "barren" world, it is highly habitable and supports microscopic life.
Why is this a Barren?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.

Contributing Factors
water89
Abundant liquid water at surface temperature (low gravity lets water escape to space)
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection
