Ross 128 b Surface Gravity Compared to Earth

With a radius about 1.1 times that of Earth, Ross 128 b would likely have a surface gravity of approximately 10.945 m/s², which is only slightly higher than Earth's gravity.

What is The Surface Temperature of Ross 128 b

The equilibrium temperature of Ross 128 b is estimated to be about 70 degrees Fahrenheit (21 degrees Celsius), making it potentially conducive to the development of life. However, the actual temperature depends on atmospheric parameters, which are currently unknown.

Does Ross 128 b Have Oxygen

As of the available data in 2017, it is not confirmed whether Ross 128 b has an atmosphere, and the presence of oxygen remains uncertain. Future observations from advanced telescopes may provide more information.

Is Ross 128 b Habitable

Ross 128 b is considered a potentially habitable world due to its size, temperature, and location within the habitable zone of its host star. It is located 20 times closer to its star than Earth is to the Sun, with an equilibrium temperature that suggests it could support liquid water if it has an atmosphere.

Ross 128 b Atmosphere Composition

As of 2017, the atmosphere composition of Ross 128 b is unknown because it does not transit its host star. Future observations, particularly with instruments like the James Webb Space Telescope, may provide insights into its atmosphere and potential biosignatures.

Ross 128 b Distance from Earth in Light Years

Ross 128 b is located approximately 11 light-years away from Earth.
