Zvijezda je stara 2 milijarde godina, dakle 2,6 milijardâ godina mlađa od Sunca. Obilježja. Although most of this radiation is emitted in the infrared (IR), it is most likely enough to allow for liquid water on the planetary surface. The size and density are not known yet which leaves the possibility that GJ667Cc after all could be an inhabitable gas planet. 10. The Earth is located in the habitable zone around the Sun at a distance of 1 AU (astronomical unit). The surface temperature, which is the most important factor in the ESI, depends much on the distance to the host star. Otkriven je 21. studenog 2011., a potvrđen 2. veljače 2012. OSLO It would rotate synchronously and show always the same side towards the star – an effect that we know from our Moon. Examples are the so-called tardigrades, which are also known under the charming names “waterbears” and “moss piglets” (see Figure 4). Flares on M-dwarfs, however, can be a thousand times stronger than compared to our Sun. No, mnogo veći dio planeta nastanjiv je ako posjeduje atmosferu koja bi premještala vruć i hladan zrak te izjednačavala temperature. Jeden tamější rok trvá něco přes 28 dní a teplota na povrchu je odhadována na 4 °C. The HARPS search for southern extra-solar planets XXXV. M-dwarfs are currently investigated here at the Institute of Theoretical Astrophysics. Comparison of the planets that are currently the promising candidates for potentially habitable worlds. Credit: http://tardigrades.bio.unc.edu. Consequently, the atmospheric pressure at the planetary surface is likely to be higher. Flares on the Sun are known to have a direct impact on our Earth and can, for instance, cause problems with satellite and radio communication. The short distance lets the star appear much larger on the sky of GJ667Cc than the Sun on our sky. Gliese 667 Cc prima protok zračenja koji iznosi oko 90% onoga što na Zemlji primamo od našeg Sunca. Temperatura bi mogla biti ugodnih 30 °C ako pretpostavimo planetarnu atmosferu sličnu zemaljskoj. Owing to the much lower energy output, the habitable zone around the red dwarf star GJ667Cc is much closer to this star at distances between 0.11 AU and 0.23 AU (see Figure 2). Consequently, there could be eternal day on the hemisphere towards the close-by star and eternal night on the other side, which is facing outer space. Planet ima masu 3,7 puta veću od mase Zemlje, a orbitalni period je 28 dana. +47 22 85 65 05 Sem Sælands vei 13 Gliese 667 Cb è stato scoperto nel 2009 e Gliese 667 Cc fu prima menzionato nel 2011, mentre nel febbraio del 2012 studi effettuati dall'Università Georg-August di Gottinga hanno portato all'annuncio della scoperta ufficiale del pianeta che sembra essere un candidato serio per essere tra quelli in grado di avere acqua liquida in superficie. Fortunately, the planet GJ667Cc is located eight times closer to its star (at 0.12 AU), which puts GJ667Cc comfortably into the habitable zone. Budući da je planet vjerojatno plimno vezan, možda je prevruć na jednoj, a prehladan na drugoj te je dobro samo u "terminator liniji". This red dwarf star therefore emits  much less radiation than the Sun, reaching a luminosity of only just over one percent of the solar value. Gliese 667 Cc je extrasolární planeta v trojhvězdném systému Gliese 667 v souhvězdí Štíra vzdáleném 23,62 světelných let od Země (7,241 parseků).Je o 54 % větší než Země (přesná hmotnost zůstává neznáma) a obíhá hvězdy v ideální vzdálenosti v tzv. We can only speculate how fauna and flora – if present at all – would evolve under such different conditions. 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. 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. The HARPS search for southern extra-solar planets XXXI. Stránka byla naposledy editována 12. In the case that GJ667Cc is a rocky planet, the gravitational acceleration on the surface would be up to 60% higher than what we experience on the surface of Earth. Točna temperatura na površini je ipak neizvjesna i ovisi o nizu još nepoznatih čimbenika. Největší z nich, oranžový trpaslík Gliese 667 A spektrální třídy K3V je o 73 % lehčí, o 76 % menší a 8× méně svítivější než Slunce. 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). 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. A more massive atmosphere, however, would result in higher temperatures and Venus-like conditions, which are unfavorable for life. Figure 3: The Sun seen from Earth (left) and an impression of how the red host star could look from the surface of the planet Gliese 667Cc (right). The Earth would be an iceworld if it orbited this star instead of our Sun. The two other stars Gliese 667A and B would be visible on the sky, see upper left corner on the picture to the right.

Being on GJ667Cc would certainly be a quite different experience. Although GJ667Cc is located in a habitable zone, the conditions on the planet could be very different from our Earth. Najsličniji je planet Zemlji iz kataloga Gliese, s sličnošću od 85%, i jedan od najsličnijih općenito. Even if the conditions on GJ667Cc might not be favourable for most terrestrial life forms, it certainly leaves room for the imagination. The zone around a star, where the surface temperature allows for the existence of liquid water on the planetary surface, is called habitable zone. These tiny creatures range in size from just 0.1 mm up to 1.5 mm. Norway, P.O box 1029 Z povrchu planety by se daly pozorovat tři západy „slunce“. Furthermore, a heavier planet can keep a more massive atmosphere. Gliese 667 Cc [3], [1], [4] (également connue sous la dénomination GJ 667Cc ou HR 6426Cc) est une planète extrasolaire (exoplanète) confirmée de type super-Terre, en orbite autour de l'étoile Gliese 667 C, une naine rouge qui est elle-même un membre du système de trois étoiles Gliese 667 situé à une distance d'environ 22,7 années-lumière, dans la constellation zodiacale du Scorpion. Less than 20 years ago before the discovery of the first exoplanets, we could only speculate about the possible existence of such planets. obyvatelné zóně, kde se může voda vyskytovat v kapalném skupenství. a planet that is slightly larger and heavier than our Earth. It orbits a type of star which is studied at the Institute of Theoretical Astrophysics. Iako se većina ovog zračenja emitira u infracrvenom (IC) zračenju, najvjerojatnije je dovoljno da se omogući tekuća voda na površini planeta. The M-dwarf sample, submitted to Astronomy & Astrophysics. They tolerate extreme temperatures and high radiation doses. 2020 v 11:47.

The Earth Similarity Index (ESI) describes how similar an object is to Earth and ranges from zero (no similarity) to one (identical to Earth). If GJ667Cc has an atmosphere that scales proportional to the terrestrial one, then the pressure would just be a few times higher. Gliese 667 Cc dio je sustava Gliese 667, koji se sastoji od 3 zvijezde. Life on the surface of GJ667Cc would have to find a solution for this problem, especially since the planet is close to its flaring host star. Planeta je svými parametry dosti podobná té naší a teoreticky by na ni mohl být život. Zahvaljujući mnogo nižem energetskom ishodu, naseljena zona oko crvene patuljaste zvijezde Gliese 667 C mnogo je bliža (između 0,11 i 0,23 AJ). O něco menší hvězda, také oranžový trpaslík pojmenovaný Gliese 667 B spektrální třídy K5V je o 69 % menší a 20× méně svítivější. The extra-solar planet GJ667Cc (or Gliese 667Cc) has been declared the most Earth-like object known outside of our solar system. A person with a weight of 75 kg on Earth would thus weigh 120 kg on the Super-Earth. 22,1 Lichtjahre von der Erde entfernt und enthält neben Gliese 667 Cc noch mindestens einen weiteren Planeten: Gliese 667 … Such mega-flares can double the brightness of the star in minutes. They can survive years without water and a 1000 times more radiation than other animals. Der Exoplanet hat eine Mindestmasse von wenigen Erdmassen und liegt in der habitablen Zone.Das System ist 6,8 Parsec bzw. Even on our own planet we find species that show an amazing ability to adapt to extreme conditions. Gliese 667 Cc je egzoplanet koji orbitira crvenog patuljka Gliese 667 C, koji je dio sustava Gliese 667. Liquid water is considered to be one of the most essential requirements for the formation of life. Gliese 667 Cc (auch GJ 667 Cc) ist ein Exoplanet, der den Roten Zwerg Gliese 667 C im Dreifach-Sternsystem Gliese 667 im Sternbild Skorpion umrundet. Gliese 667Cc is located in the habitable zone of its host star and is currently the most Earth-like planet known (ESI=0.82). Planet ima masu 3,7 puta veću od mase Zemlje, a orbitalni period je 28 dana. GJ667Cc receives a radiation flux which is about 90% of what we receive from our Sun on Earth. Figure 2: See here for a larger version. They are found in hot springs, ocean sediments, under ice sheets and even on top of the Himalayas. Jedna grupa znanstvenika smatra kako bi dugoživci mogli preživjeti na ovom planetu. The planet GJ667Cc is even more similar to our Earth than Kepler-22b, which was confirmed as a potentially habitable planet just a few weeks ago. Nature proves to be inventive though. Our Sun would also be seen with the naked eye as a distant star. Otkriven je 21. studenog 2011., a potvrđen 2. veljače 2012. Ačkoliv se planeta nachází v obyvatelné zóně, tak kvůli složení spektrálních tříd svých hvězd získá jen 90 % energie než to, co obdrží Země. The two other stars Gliese 667A and B would be visible on the sky, see upper left corner on the picture to the right. Figure 4: Tardigrades or “waterbears” are examples for animals that can exist and develop under extreme conditions here on the Earth. No, masivnija atmosfera bi rezultirala višim temperaturama i uvjetima nalik Veneri, koji su nepovoljni za život. 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. More details about this discovery are available in the HEC project area of the PHL website. These hardened creatures have even been returned alive from studies in low earth orbit where they were exposed to space conditions. The M-dwarf sample, A planetary system around the nearby M dwarf GJ 667C with at least one super-Earth in its habitable zone, The HARPS search for southern extra-solar planets XXXV. Many M-dwarf stars – among them GJ667C – are known to emit flares, which are intense bursts of radiation and energetic particles.

This would make it possible to celebrate your 1000th birthday (which is just 77 years on Earth). 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. The temperature could be a pleasant 30°C if we assume a planetary atmosphere that is similar to the Earth’s. Ova stranica posljednji je put uređivana 22. prosinca 2019. u 15:34. Prve dvije (A i B) su zvijezde K tipa, dok je treća (C), M3V tipa, a svi planeti, uključujući i Gliese 667 Cc kruže oko nje.
