TRAPPIST-1e is the TRAPPIST-1 planet most likely to have water and is in a comparable position within the habitable zone to Proxima Centauri b. It also has an Earth-like density. TRAPPIST-1e could have kept up to several Earth ocean masses of water.

What is the most habitable planet in the TRAPPIST system?
TRAPPIST-1f, the fifth planet from the host star, is located in the habitable zone, a region where liquid water is most likely to be found. This planet is slightly larger in size but less massive than Earth, and completes an orbit every nine days.
Which TRAPPIST planets are in the habitable zone?
Three of them — TRAPPIST-1e, f and g — are located in the habitable zone of the star (shown in green in this artist's impression), where temperatures are just right for liquid water to exist on the surface.
Are the planets in the TRAPPIST-1 solar system habitable?
An international scientific team led by Patrick Barth from the University of St. Andrews in Scotland evaluated the planetary evolution of three planets in the Trappist-1 system, a family of exoplanets just 40 light years away from Earth. All three planets are considered to be potentially habitable.
Is TRAPPIST-1b in the habitable zone?
While TRAPPIST-1b, c and d are too close to be in the system's likely habitable zone, and TRAPPIST-1h is too far away, the planets' discoverers say more optimistic scenarios could allow any or all of the planets to harbor liquid water.
Can we live on TRAPPIST-1e?
From what scientists know, TRAPPIST-1e is the most likely to be habitable. It has the most Earth-like ocean world and would be an excellent choice for further study with habitability in mind.
Is there oxygen on TRAPPIST-1e?
A new study published today in the Planetary Science Journal shows that the TRAPPIST-1 planets have remarkably similar densities. That could mean they all contain about the same ratio of materials thought to compose most rocky planets, like iron, oxygen, magnesium, and silicon.
Is there life on TRAPPIST-1e?
Furthermore, according to the Habitable Exoplanets Catalog, TRAPPIST-1e is one of the most potentially habitable exoplanets discovered….TRAPPIST-1e.

Can TRAPPIST-1 sustain life?
According to these models, the seven planets of TRAPPIST-1 would have dense, uninhabitable atmospheres. However, one of the worlds, called TRAPPIST-1e, may host liquid water on its surface and, as a result, be able to support Earth-like life, according to the statement.
Is Kepler 16B habitable?
It is not habitable as we know it. Kepler 16B is an exoplanet that orbits in the system of two stars in the Cygnus Constellation. It completes its orbits of two stars within the period of 229 earth days.
