description TRAPPIST-1g Overview
TRAPPIST-1g is an Earth-sized exoplanet orbiting the TRAPPIST-1 star. Its notable size, approximately 1.13 times that of Earth, and location within the habitable zone make it a key target in the search for potentially life-supporting worlds. Scientists study this rocky planet to assess its atmospheric composition and determine if conditions suitable for liquid water exist. Research focuses on understanding the planet's environment and potential habitability for future exploration.
help TRAPPIST-1g FAQ
What makes TRAPPIST-1g a good candidate for potential habitability?
TRAPPIST-1g is an Earth-sized exoplanet located squarely within the habitable zone of its ultracool dwarf star. Its radius is approximately 1.13 times that of Earth, suggesting it is a rocky world that could theoretically harbor liquid water on its surface.
How far away is the TRAPPIST-1 system from Earth?
The TRAPPIST-1 system is located about 40 light-years away from Earth in the constellation of Aquarius. This relatively close distance in astronomical terms makes it a prime target for observations by telescopes like the James Webb Space Telescope.
What type of star does TRAPPIST-1g orbit?
TRAPPIST-1g orbits an ultracool red dwarf star known as TRAPPIST-1. Because this host star is much cooler and smaller than our Sun, the planet's habitable zone is positioned very close to the star.
How long does it take for TRAPPIST-1g to orbit its star?
Because the planet orbits extremely close to its host star, a year on TRAPPIST-1g takes only about 12.4 Earth days. All seven planets in the TRAPPIST-1 system have very short orbital periods due to their tight proximity to the red dwarf.
