Kepler-442b, 1,100 light-years away, is 33 percent bigger than Earth and orbits its star once every 112 days. Kepler-442b (also known by its Kepler object of interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type main-sequence star Kepler-442, about 1,206 light-years (370 parsecs), from Earth in the constellation Lyra. Nearby stars with planets can then be studied by the upcoming James Webb Space Telescope and future large ground-based telescopes to analyze atmospheres, determine masses and infer compositions. The ideal. Its metallicity, estimated at −0.37, is lower than that of the Sun, indicating a relative lack of heavy elements. Watch Queue Queue The orbit of Kepler-22b around its star takes 289 days and is about 85 percent as large as Earth's orbit. The planet receives powerful radiation from its parent stars every 100 days. Otkriven je i potvrđen 6. siječnja 2015., i to tranzitom. It is expected to be a rocky planet with mass 2.34 times that of Earth. Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. [9] Because of their high stellar activity at the beginning of their lives, they emit strong solar winds. Kepler-442b is also the most similar known case of a superhabitable planet. Until its discovery in 2015, the Kepler telescope had only detected 12 Earth-size planets (smaller than twice the size of Earth) in the habitable zone of their smaller and cooler stars. NASA announced the confirmation of the exoplanet on 6 January 2015. Het was de eerste gevonden exoplaneet rond een op onze zon gelijkende ster. The mass and composition of Kepler 452b are unknown at this time but its small size indicates that it is most probably a rocky planet. It was described as being one of the most Earth-like planets, in terms of size and temperature, yet found. Kepler-452b ist unserer Erde verblüffend ähnlich. While the planet is estimated to have an equilibrium temperature of -2.65°C, the actual temperature of the planet depends on both the albedo and the greenhouse effect of the atmosphere of Kepler-442 b, which are unknown. [1] Its luminosity (L☉) is 11% that of the Sun. Kepler 442b (ESI=0.84) is a planet 1.3 times the size of Earth discovered in 2015. NASA's Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. Die Entdeckung des Exoplaneten Kepler-452b begeistert nicht nur Forscher. This page was last modified on 8 May 2016, at 18:05. At nearly 370 parsecs (1206 LY) distant, Kepler-442b is too remote and its star too far for current telescopes or the next generation of planned telescopes to determine its mass or whether it has an atmosphere. Extrapolated from the information given in, Habitability of K-type main-sequence star systems, Tidal effects on rotation rate, axial tilt, and orbit, "HEC: Data of Potential Habitable Worlds", "Kepler 438b: Most Earth-like planet ever discovered could be home for alien life", "NASA's Kepler Marks 1,000th Exoplanet Discovery, Uncovers More Small Worlds in Habitable Zones", "Planetary Habitability Laboratory at University of Puerto Rico", "HEC: Data of Potentially Habitable Worlds - Planetary Habitability Laboratory @ UPR Arecibo", "Red Dwarf Stars May Be Best Chance for Habitable Alien Planets", "Can Life Thrive Around a Red Dwarf Star? This is close enough that the planet gets about two thirds of the amount of sunlight as Earth does. Kepler 442b is confirmed in close proximity to the earth-shaped exoplanet. Kepler-442b (also known by its Kepler object of interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type main-sequence star Kepler-442, about 1,206 light-years (370 parsecs), from Earth in the constellation Lyra. Both Kepler-438b and Kepler-442b orbit stars smaller and cooler than our sun, making the habitable zone closer to their parent star, in the direction of the constellation Lyra. Kepler 438B has resulted in radiation in large quantities from its wire. A superhabitable planet would have shallow oceans. [2][3] Der Planet wurde durch das Weltraumteleskop Kepler der NASA mit Hilfe der Transitmethode entdeckt, wobei die geringfügige Verfinsterung des Sterns beim Vorüberziehen des Planeten gemessen wird. These stars are not only smaller but also cooler when compared to the sun. These stars are fainter and cooler than our Sun, and 7.5% to 50% as massive. The star that Kepler 452b orbits is very similar to our sun. The star has a mass of 0.61 M☉ and a radius of 0.60 R☉. The planet orbits a (K-type) star named Kepler-442. Its orbit is probably close to circular (eccentricity 0.04) so it will also lack eccentricity-induced seasonal changes like those of Mars. Kepler 442b is known to be one of the planets of all planetary. By K.G Orphanides. Kepler 438B produces more powerful stars than the Sun. That still seems pretty bad-- Mars gets 44% as much sunlight as Earth does, and it is really cold-- but luckily, 442b is larger than the Earth. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another “Earth.” Kepler-442b (also known by its Kepler Object of Interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type star[6] Kepler-442, about 1,120 light-years (342 pc) from Earth in the constellation Lyra. Kepler-442b je egzoplanet koji orbitira zvijezdu K-tipa Kepler-442.Otkriven je i potvrđen 6. siječnja 2015., i to tranzitom.Uz njega su još objavljeni i planeti Kepler-440b i Kepler-438b.Udaljen je 1206 svjetlosnih godina. It is thought that the force of gravity on Kepler 452b would be twice as strong as Earth's gravity. Looking at the star of Kepler 438 B with a naked eye is almost unclear. Top 10 Recently Discovered EARTH LIKE PLANETS, Kepler 69c Earth Size Planet in Star's Habitable Zone, 10 BEAUTIFUL Latest Earth Like Planets FOR HUMANS. Kepler-442 b, planet, semi-major axis: 0.41 +0.06 −0.21 AU. [7] As of July, 2018, Kepler-442b was considered the most-habitable non-tidally locked exoplanet discovered.[11]. Planets in the system. Until its discovery in 2015, the Kepler telescope had only detected 12 Earth-size planets (smaller than twice the size of Earth) in the habitable zone of their smaller and cooler stars. Its discovery was announced in 2015. ESI Rating –.84. We have created a browser extension. [4][5] It is outside of the zone (around 0.02 AU) where tidal forces from its host star would be enough to tidally lock it. NASA's Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. Kepler input catalogs contain 50,000 stars. Constellation – Lyra. [7] The surface gravity on Kepler-442b would be 30% stronger than that of Earth, assuming a rocky composition similar to that of Earth.[8]. Kepler-442 b is a super Earth exoplanet that orbits a K-type star. It's thus in a more energetic phase of its life cycle than the sun is; indeed, the star is about 10 percent larger and 20 percent brighter than Earth's sun. The discovery, along with the notable planetary systems of the stars Kepler-438 and Kepler-440, were announced on 6 January 2015.[1]. Kepler-452b is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years from Earth in the constellation Cygnus. Kepler 452b is considered the most Earth like planet yet discovered due to its size, location in its system and the type of star it orbits. Both Kepler-438b and Kepler-442b orbit red dwarf stars that are smaller and cooler than our sun.

It is very unclear to see this planet with a naked eye from Earth.Kepler 442b is circuits with its host star with a radius of 0.4 times the Earth's orbit with 112.3 days of rotation. This planet was revealed to be located in its habitable zone. Its mass is 2.36 Earths, it takes 112.3 days to complete one orbit of its star, and is 0.409 AU from its star. After observing the respective transits, which for Kepler-442b occurred roughly every 113 days (its orbital period), it was eventually concluded that a planetary body was responsible for the periodic 113-day transits. Kepler-442b (also known by its Kepler Object of Interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type star Kepler-442, about 1,120 light-years (342 pc) from Earth in the constellation Lyra. As of July, 2018, Kepler-442b was considered the most-habitable non-tidally locked exoplanet discovered. The scientists give it a 97 percent chance of being in the habitable z… [10] Kepler-442b orbits a K-type star 0.2 AU outside of the zone where gravitational tug would be strong enough to tidally lock it.[11]. The planet was announced as being located within the habitable zone of Kepler-442, a region where liquid water could exist on the surface of the planet. An artist’s impression of Kepler-442b. Kepler-442b may have oceans. The atmosphere of Kepler-442b is unknown.
