Tau Ceti e is among the top closest exoplanets to our solar system, therefore its distance from our solar system is reasonable.
1.12582690 x 10^14 km
With all of the mentioned reasons and the close similarity to Earth (1), this planet is habitable.
This planet is predicted to be a rocky planet with poor soil conditions which vegetation does not grow in.
The rocky ground/zone and heat make vegetation on this planet really difficult.
This exoplanet is just generously within the habitable zone and Earth is in a better position than Tau Ceti e is which means temperatures could be higher than we are used to.
In the end, this exoplanet lies too close to the inner edge of the habitable zone distance, making the temperatures a little high for habitability.
Better than Earth’s composition, contains certain minerals that are most important rock-forming minerals (magnesium, silicon) on Earth.
With an almost ideal zone composition, based on this category, Tau Ceti e is habitable.
Tau Ceti e's atmosphere is close to 0: somewhat dense but close to ideal for habitability.
The slightly dense, but close to perfect, atmosphere makes this planet habitable.
This exoplanet has a similar planetary class to what humans are used to which can make it livable.
The similarity between Tau Ceti e's planetary class and Earth makes this planet livable.
This exoplanet receives more light from Tau Ceti (its star) than Earth does from Sun, making it somewhat habitable for heat-lovers.
With this planet having the same range of temperatures as Earth, Tau Ceti e is habitable.
Pros include habitable zone composition, habitable zone atmosphere, planetary class, habitable class and distance.
Cons include suitability for vegetation and habitable zone distance.
Mesoplanets: medium temperature (0-50℃)
Thermal Zone: [W]- Warm (habitable zone)
Tau Ceti possesses a somewhat dense atmosphere, similar to our gas giants, trapping most of the heat coming from the star and making it less hot and bearable.
Earth's atmosphere is -0.52, thin and worse than that of Tau Ceti e.
x 3.93 =
#1: In the night sky, Tau Ceti is visible to the naked eye.
#2: Tau Ceti has been mentioned in multiple sci-fi movies because of its potential future habitability.
(Same Thermal Zone)
The categories of Similarity to Earth, Habitable Zone Distance, Composition and Atmosphere, Planetary Class, Habitable Class and Distance from Earth make this planet potentially habitable, however two main categories, Suitability for Vegetation and Habitable Zone Distance make this planet inhabitable.
In the end, Life and Human Colonization are possible on this planet.
1. Suitability For Vegetation: With advanced technology and developed space travel, in the future, vegetation could be transported from Earth.
2. Habitable Zone Distance: The real issue are the high temperatures because of this planet's close distance to its star. This can be solved by releasing gases into the air which thicken the atmosphere, trap heat and make temperatures livable.
of the categories make this planet livable!
Habitable Zone Composition
Above categories are all similar to Earth which contributes to the high Earth-Like Index and means
that we will be used to most conditions on Tau Ceti e.
The size is unknown meaning that it's not possible to tell the planet is a rocky, water or gas world but is potentially rocky Earth based off predictions.
Close to the ideal mixture of iron-rock-water but might contain a little more iron/rock.
Luminosity: 0.45 L☉
Luminosity: 1 L☉
Distance From Star: 0.538 AU
Exoplanet could reach high temperatures, which vegetation does not grow in.
