Sentences with phrase «zone planets»

The phrase "zone planets" refers to planets that are located in a specific area of a star system where conditions may support the existence of life. These planets are situated in a region called the "habitable zone" or "goldilocks zone," where they are neither too hot nor too cold to have liquid water, making them potentially suitable for living organisms.

Assuming that the frequency of observed habitable zone planets really is a result of stellar age, this begs the question of whether the planets currently observed in the habitable zone really formed there or whether they were brought into it as their star evolved.
Sen — Three astronomers from the Universidade do Porto, Portugal have begun tackling a very large and multi-dimensional question: How is the frequency of small habitable zone planets dependent on the properties of the host star?

While star system Proxima Centauri is a more sensible choice for an interstellar voyage, since it also contains a rocky, habitable - zone planet and is much closer to Earth (4.22 light years away), the opportunity to find life on multiple worlds in the TRAPPIST - 1 system increases its chances of a visit someday.
In Project 3.2, we will simulate the accretion of terrestrial planets in order to understand the amount of biocritical elements that would be delivered to habitable zone planets.

Future exoplanet missions like NASA's Transiting Exoplanet Survey Satellite (TESS), and European Space Agency's CHaracterising ExOPlanet Satellite (CHEOPS) and PLAnetary Transits and Oscillations of stars (PLATO - 2.0) missions will bring in even more data than Kepler and help us fill out the ranks of small habitable zone planets.
However, our exoplanet surveys have only just begun to detect enough habitable zone planets to attempt this type of analysis, and our understanding of stellar metallicity and planet formation is still too limited to make any firm conclusions.
