Astronomers from the Brazilian National Observatory of Rio de Janeiro have discovered that on the planet Ross 128b in the constellation Virgo is similar to the earth's subsoil and mild climate. And so, according to scientists, life could exist there
The research was published in the journal Astrophysical Journal Letters, briefly described by space.com. It means that there can be life on the surface of the celestial body.
In 2017, astronomers reported the discovery of a planet resembling the Earth just 11 light-years from Earth. The celestial body, called the Ross 128b, has a minimum mass of about 1.35 terrestrial and is 20 times closer to its parent star than our planet to the Sun.
An exoplanet revolves around the inactive red dwarf Ross 128, which unlike most similar objects, much more rarely known powerful flashes. In addition, according to preliminary estimates, the planet has a temperate climate, which means that the surface temperatures are favorable to the existence of a potential life.
The mass of the ocean is 1.3 times greater than the mass of the ocean. It is about 5 billion years old, which means that the planet has already established a mild and homogeneous climate without sudden changes in temperature and excessive seismic activity.
Astronomers have observed that on the surface of the star Ross 128 observes a hot planet through the APOGEE telescope. about the same amount of carbon, titanium, and iron as the Sun. This means that the planet that revolves around the red dwarf is similar to that of the interior of the Earth and the nucleus.
If the Ross 128b albedo, which characterizes the reflectivity of the celestial body, is similar to the albedo of the Earth, the average temperature is 294 ± 10 Kelvin (20 degrees Celsius). If the Ross 128b looks more like Mars or Venus, the equilibrium temperature will be 299 ± 11 or 223 Kelvin, respectively (25 or -50 degrees Celsius)
However, there is now a hypothesis on the Appearance of the planet and its contents. the climate is based solely on estimates of its mass and distance from the parent star. Indirect methods can help to get more information on the planet, for example, the analysis of the chemical composition of Ross 128.
