TRAPPIST-1f Surface Gravity Compared to Earth

TRAPPIST-1f has a surface gravity of approximately 0.951 times that of Earth, equivalent to 9.32¬†ÔŅĹ/ÔŅĹ2.

Surface Temperature of TRAPPIST-1f

The equilibrium temperature of TRAPPIST-1f is approximately 217.7¬†ÔŅĹ, which is equivalent to ‚ąí55.5¬†¬įÔŅĹ or ‚ąí67.8¬†¬įÔŅĹ.

Does TRAPPIST-1f Have Oxygen?

The information provided does not specify whether TRAPPIST-1f has oxygen or not. The composition of an exoplanet's atmosphere is often challenging to determine without direct observational data.

Is TRAPPIST-1f Habitable?

TRAPPIST-1f orbits within the habitable zone of its parent star, and there is evidence of possible water content on the TRAPPIST-1 exoplanets. However, the habitability is subject to debate. Initially considered somewhat unlikely to be Earth-like due to its mass, refined estimates suggest it has about the same mass as Earth.

TRAPPIST-1f Atmosphere Composition

According to simulations, TRAPPIST-1f is likely to retain a fraction of a primordial steam atmosphere during its evolution. It is suggested to possess a thick ocean covered by an atmosphere rich in abiotic oxygen. Helium emission from TRAPPIST-1f has not been detected as of 2022.

TRAPPIST-1f Distance from Earth in Light Years

TRAPPIST-1f is located approximately 40.7 light-years away from Earth in the constellation of Aquarius.

10 Interesting Fun Facts About TRAPPIST-1f

  1. Waterworld Characteristics: TRAPPIST-1f is nicknamed "The Waterworld" due to its significant water content, with about a fifth of its mass estimated to be water.
  2. Orbiting a Red Dwarf: It orbits an ultracool dwarf star, TRAPPIST-1, with only about 8% of the mass of the Sun.
  3. Equilibrium Temperature: Despite its proximity to the star, TRAPPIST-1f has a low equilibrium temperature of ‚ąí55.5¬†¬įÔŅĹ.
  4. Tidally Locked: The planet is likely tidally locked, with one hemisphere permanently facing the star.
  5. Eyeball Planet: Artistic impressions depict TRAPPIST-1f as an eyeball planet due to its likely tidally locked nature.
  6. Potential Thick Atmosphere: The presence of a powerful hydrosphere and tidal entrainment could lead to water evaporation, forming a thick atmosphere.
  7. Habitability Debate: Initial estimations and simulations suggested low habitability, but refined estimates indicate it has a mass similar to Earth, raising questions about its potential habitability.
  8. Metal-Rich Host Star: TRAPPIST-1f's host star is metal-rich, with a metallicity ([Fe/H]) of 0.04.
  9. Potential for Liquid Water: The terminator line, the boundary between light and dark sides, might have suitable temperatures for liquid water if the atmosphere is thick enough.
  10. Discovery: Discovered using the transit method and announced in 2017, TRAPPIST-1f is one of four new exoplanets found around the TRAPPIST-1 star using observations from the Spitzer Space Telescope.
