Nevertheless, these two stars would be prominently visible on the sky. Together with the fact that the red dwarf star emits almost no ultraviolet light, these varying light conditions could be a potential problem for the formation of life as we know it. 10. Being on GJ667Cc would certainly be a quite different experience. https://hr.wikipedia.org/w/index.php?title=Gliese_667_Cc&oldid=5392662, Creative Commons Imenovanje/Dijeli pod istim uvjetima, Umjetnički prikaz zalaska na planetu, s Glieseom 667 AB u pozadini. Super-Earths around the M-dwarf neighbors Gl433 and Gl667C, submitted to Astronomy & Astrophysics, Svein Rosselands hus (map) No, masivnija atmosfera bi rezultirala višim temperaturama i uvjetima nalik Veneri, koji su nepovoljni za život. Like Kepler-22b, GJ667Cc is a Super-Earth, i.e. Further observations are needed to answer if GJ 667Cc truly supports liquid water and if the conditions on this planet are appropriate for hosting life. Gliese 667 Cc dio je sustava Gliese 667, koji se sastoji od 3 zvijezde. Z toho je většina infračervené záření a pouze 18 % viditelné světlo. Potrebna su dodatna zapažanja kako bi se odgovorilo podržava li Gliese 667 Cc tekuću vodu i jesu li uvjeti na ovom planetu prikladni za život. The star casts a faint reddish light on the planet’s surface. For a more extreme case like a Venus-type atmosphere, the pressure could be several hundred times larger, which corresponds to a water pressure a few kilometres deep down in the ocean on Earth. Gliese 667Cc is located in the habitable zone of its host star and is currently the most Earth-like planet known (ESI=0.82). Less than 20 years ago before the discovery of the first exoplanets, we could only speculate about the possible existence of such planets. Z povrchu planety by se daly pozorovat tři západy „slunce“. Life would be facing some potential challenges, which may include low and varying light conditions, possibly a higher atmospheric pressure, and violent flares. Otkriven je 21. studenog 2011., a potvrđen 2. veljače 2012. Ova stranica posljednji je put uređivana 22. prosinca 2019. u 15:34. Planeta je svými parametry dosti podobná té naší a teoreticky by na ni mohl být život. O něco menší hvězda, také oranžový trpaslík pojmenovaný Gliese 667 B spektrální třídy K5V je o 69 % menší a 20× méně svítivější. Zemlja bi bila ledeni svijet kada bi orbitirao oko ove zvijezde umjesto našeg Sunca. One year on this planet is thus only 28 Earth days long. Planet ima masu 3,7 puta veću od mase Zemlje, a orbitalni period je 28 dana. Although GJ667Cc is located in a habitable zone, the conditions on the planet could be very different from our Earth. Fortunately, the planet GJ667Cc is located eight times closer to its star (at 0.12 AU), which puts GJ667Cc comfortably into the habitable zone. The temperature differences between both sides could be large and could affect the global climate. Iako se većina ovog zračenja emitira u infracrvenom (IC) zračenju, najvjerojatnije je dovoljno da se omogući tekuća voda na površini planeta. A planetary system around the nearby M dwarf GJ 667C with at least one super-Earth in its habitable zone, to appear in Astrophysical Journal Letters. Consequently, the atmospheric pressure at the planetary surface is likely to be higher. 2020 v 11:47. Although the star is much smaller than the Sun, it would appear larger on the sky and cast a faint reddish light on the planet’s surface. The distance to other two stars Gliese 667A and B is about 230 AU, which is about six times the distance between Pluto and the Sun and clearly outside the planetary system around Gliese 667C. It would rotate synchronously and show always the same side towards the star – an effect that we know from our Moon. The temperature could be a pleasant 30°C if we assume a planetary atmosphere that is similar to the Earth’s. The higher mass of this planet results in a different gravitational acceleration (that’s what keeps us on the ground) compared to our Earth. Most stars that host exoplanets are thus expected to be cool M-dwarfs, which makes the case of GJ667Cc particularly interesting. 0315 Credit: S. Wedemeyer, University of Oslo (2012). Only a more compact rocky or ocean planet with a corresponding radius between about 1.7 and 2.2 Earth radii would be favorable for the formation of life. Drugi je otkriven planet u tom sustavu. No, mnogo veći dio planeta nastanjiv je ako posjeduje atmosferu koja bi premještala vruć i hladan zrak te izjednačavala temperature. They can survive years without water and a 1000 times more radiation than other animals. They are found in hot springs, ocean sediments, under ice sheets and even on top of the Himalayas. Examples are the so-called tardigrades, which are also known under the charming names “waterbears” and “moss piglets” (see Figure 4). Jeden tamější rok trvá něco přes 28 dní a teplota na povrchu je odhadována na 4 °C. Gliese 667 Cc (anvet ivez GJ 667Cc pe c'hoazh HR 6426Cc), a zo un egzoplanedenn hag a zo he mas etre mas an Douar ha hini ur blanedenn ramzel. The zone around a star, where the surface temperature allows for the existence of liquid water on the planetary surface, is called habitable zone. Unfortunately, there is a potential problem with the nearby host star. Gliese 667 Cc má celkem tři mateřské hvězdy. M-dwarfs are currently investigated here at the Institute of Theoretical Astrophysics. The red dwarf would be seen as a red disk that, in comparison to the Sun, is about 3 times as wide and covers about 10 times the area (see Figure 3).
