The discoveries of exoplanets have become fast and furious for several years, thanks in large part to the increasingly powerful telescope technology that allows us to study the sky in more detail than ever before. Many of the exoplanets that astronomers locate are very clearly inhospitable to life because of their distance from their star, or the chemical signatures that we are able to detect from afar, but Ross 128b, located 11 light-years away, is very different. 19659002] Ross 128b is a planet orbiting the star Ross 128 (see how does it work?), And it's in the area called "halos", which is the distance from its star host which would make its surface neither more nor too cold to sustain life. Scientists already know the location of Ross 128b for some time now, but new research gives even more weight to the theory that the planet could actually look like the Earth

In a planetary system, the star and the planets that surround it are largely made of the same kind of material.The star's chemical composition is a good indicator of the amount of various elements present in the planets that surround it, and scientists can study the light that the star produced to have a rough idea of what is inside. Ross 128 looks very, very promising.
The star is smaller than our Sol but it has comparable iron levels. By combining this with a measurement of the star's magnesium levels, the team was able to determine that its near planet is almost certainly rocky, like the Earth, and that it might even be larger than our own planet. Using size estimates, the levels of exposure to heat and light from the planet have also been calculated and the planet falls well within the limits to support life as we know it on Earth. the light of its star host tells us about the chemistry of the system, "explains Diogo Souto, principal investigator. "Although Ross 128B is not the twin of the Earth, and we are still unaware of its potential geological activity, we have been able to reinforce the argument that it is a temperate planet that could potentially have the same effect." 39, liquid water on its surface.
