And even though Ross 128 b is 20 times closer to its star than Earth is to the sun, the planet could still have a comfortable temperature because red dwarf stars are so much cooler, astronomers say. The exoplanet called Ross 128 b is just 11 light years away from Earth. 2019 Ross 128 b is the nearest exoplanet around a quiet red dwarf, and is considered one of the best candidates for habitability. The planet is only 35% more massive than Earth , receives only 38% more sunlight, and is expected to be a temperature suitable for liquid water to exist on the surface… The weather looks fine on nearby Earth-like planet Ross 128 b. Ross 128 b is the second closest rocky planet beyond our solar system, but it may be the nearest exoplanet worth checking for aliens. The planet – named Ross 128 b like some intergalactic David Schwimmer clone – is 35% bigger than Earth, has years lasting 9.9 days, and is 20 times closer to its star than we are to the Sun. High Accuracy Radial velocity Planet Searcher) działający w Europejskim Obserwatorium Południowym rejestrował zmiany prędkości radialnej Rossa 128, wywołane przyciąganiem planety. Let’s dig into ‘habitability’ a bit more. Niewielka odległość planety od gwiazdy sprawia, że planeta jest łatwiejsza do wykrycia, ale z drugiej strony małe natężenie światła gwiazdy utrudnia precyzyjny pomiar[4]. The exoplanet, which has been designated Ross 128 b, is 1.35 times the mass of the Earth and orbits its star at only 5 million kilometers, or 20 times closer than Earth is to the Sun. Although Ross 128 b is not Earth’s twin, and there is still much we don’t know about its potential geologic activity, we were able to strengthen the argument that it’s a temperate planet that could potentially have liquid water on its surface.” Some readers may recall there is an even closer Earth-sized planet, known as Proxima Centauri, which sits just 4.25 light years away. Follow-up observations are needed to determine whether Ross 128 b orbits within or near the habitable zone where liquid water could exist on the planet's surface. Nazwa planety pochodzi od nazwy gwiazdy, którą ciało to okrąża. Temperatura fotosfery gwiazdy to około 3190 K, jej jasność to około 0,36% jasności Słońca. Ross 128 b vs. Proxima b Red dwarfs are the most common type of star in our galaxy, and many are known to possess planetary systems. Została odkryta metodą pomiaru zmian prędkości radialnej. Most importantly, scientists say Ross 128 b may be capable of sustaining life. Dane zostały uzupełnione przez pomiary fotometryczne programu All Sky Automated Survey i z misji K2 Teleskopu Keplera[2]. Ross 128 to czerwony karzeł, gwiazda znacznie słabsza i chłodniejsza od Słońca. Ma ona masę równą zaledwie 17% masy Słońca i promień równy 20% promienia Słońca[1][2]. Planeta otrzymuje obecnie 1,38 razy więcej energii niż dociera do Ziemi. New research strengthens the argument that it’s a temperate planet in the inner edge of the habitable “Goldilocks” zone that could potentially have liquid water on its surface. Dociera do niej strumień promieniowania o 38% wyższy niż do Ziemi i temparatura równowagowa powierzchni jest szacowana na od –60 do 20 °C. The effective temperature (T eff) and surface gravity (log g) values of Ross 128 were obtained using a similar methodology as discussed in Souto et al. Its surface temperature ranges from -60º C to 20º C, which is the average range of temperatures at Vostok, Antarctica; the numbers are conducive to the presence of liquid water on the surface. Let’s dig into ‘habitability’ a bit more. from Earth, Ross 128 b is the exoplanet second closest to Earth. paper, A temperate exo-Earth around a quiet M dwarf at 3.4 parsecs 2019 . Ross 128 is a star with about half the surface temperature of the Sun. Ross 128 b circles it every 10 days or so, since it is about 20 times closer to its star than the Earth is to our sun. W 2017 roku metodą pomiaru zmian prędkości radialnej odkryto niewielką planetę krążącą wokół tej gwiazdy. It is calculated that Ross 128 b has a minimum mass of 1.35 times the Earth, and orbits 20 times closer to its star than Earth orbits the Sun, intercepting only about 1.38 times more solar radiation than Earth, increasing the chance of ret… Masa minimalna tej planety to około 1,4 masy Ziemi, co wskazuje, że jest to najprawdopodobniej planeta typu ziemskiego. Ross 128 b: Nearby earth-like planet could support alien life. The observations also suggest that, though the exoplanet is 20 times closer to its star and takes just 9.9 days to orbit it, Ross 128 b probably has a temperate climate. paper  arxiv, Dim Prospects for Transmission Spectra of Ocean Earths Around M Stars That previous study used the OH and H 2 O lines as oxygen abundance indicators to define the effective temperature. & RAUER H. As a result, Ross 128 b’s equilibrium temperature is estimated to lie between -60 and 20°C, thanks to the cool and faint nature of its small red dwarf host star, which has just over half the surface temperature of the Sun. Planeta Ross 128 b to planeta typu ziemskiego o masie 1,4 M ⊕. Ross 128 b will be a prime target for ESO’s Extremely Large Telescope, which will be able to search for biomarkers in the planet’s atmosphere. But so do Venus and Mars, if you measured them from light-years away. Statistical evidence suggests that Ross 128 b is a rocky planet, like the four innermost planets in our solar system. Ross 128 b is the second-closest planet to be detected outside the solar system with surface … Earth, with similar surface temperatures, raising hopes that it could potentially support life. An artist's impression of Ross 128 b, the second closest temperate exoplanet to Earth after Proxima Centauri b. So the planet would have a stronger pull of gravity at its surface. Astron. This is due to the cool and faint nature of red dwarf stars like Ross 128, which has a surface temperature roughly half that of our Sun. Ross 128 b’s proximity means it receives 1.38 times more energy from its star than Earth does from the Sun, even though Ross 128 is 280 times less luminous than the Sun. Ross 128 b is intriguing in many ways, but it’s just one of a growing number of such worlds. SOUTO D., UNTERBORN C., SMITH V., CUNHA K., TESKE J. et al.
