NASA.gov brings you the latest images, videos and news from America's space agency. It has an equilibrium temperature of 233 K (−40 °F). Der Planet Kepler-442b umkreist ebenfalls einen roten Zwergstern und liegt sogar mit 97 Prozent Wahrscheinlichkeit in dessen bewohnbarer Zone. It is expected to be a rocky planet with mass 2.34 times that of Earth. [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-442b, 1,100 light-years away, is 33 percent bigger than Earth and orbits its star once every 112 days. In comparison, the Sun is 4.6 billion years old[9] and has a temperature of 5778 K.[10] The star is somewhat metal-poor, with a metallicity (Fe/H) of −0.37, or 42% of the solar amount. 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. [14] However, because of the uncertainty of the age of Kepler-442, it is likely it may have passed this stage, making Kepler-442b potentially more suitable for habitability. Kepler-452 is the name of a star in the constellation of Cygnus (the swan). 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. [1][2] The planet was discovered by NASA's Kepler spacecraft using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler 452b orbits its star at a similar distance that the Earth orbits the sun. It’s a star that’s similar to our own sun, but it’s too faint for us to see from Earth without a telescope. 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. 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. Kepler-442b (Rocky Planet) : The Size Of Exoplanet With Earth Planets in the system. 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. This list shows all planetary and stellar components in the system. Kepler-452b is een exoplaneet rond de ster Kepler-452 in het sterrenbeeld Zwaan en werd in 2015 ontdekt. The newfound planet, named Kepler-452b, is around 60% larger in diameter than Earth and is 5% farther from its parent star than Earth is from the Sun. Kepler-452b ist unserer Erde verblüffend ähnlich. Otkriven je i potvrđen 6. siječnja 2015., i to tranzitom. Fizikai jellemzők Tömeg, sugár és hőmérséklet. A Kepler-442b tulajdonságai, amelyek megfelelnek a lakhatósági kritériumoknak, a következők: K típusú csillag körül kering, amely egy lakható bolygó számára a legjobb csillag típus. ... Kepler-438b sits 470 light years from Earth, and Kepler-442b is even farther away at 1,100 light years. Uz njega su još objavljeni i planeti Kepler-440b i Kepler-438b. The planet was announced as being located within the habitable zone of its star, a region where liquid water could exist on the surface of the planet. We have created a browser extension.

The duration of this period is inversely linked to the size of the star. The star's apparent magnitude, or how bright it appears from Earth's perspective, is 14.76. 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. By K.G Orphanides. Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The results were announced at the AAS meeting in 2015. Kepler-442b je Superzemlja, planet veći od Zemlje, a manji od Neptuna. NASA's Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. It is 1.5 billion years older than the Sun. Kepler-442 b, planet, semi-major axis: 0.41 +0.06 −0.21 AU. Kepler-442b’s close position to its host star (0.4x AU, or roughly as close to its star as Mercury is to the Sun) doesn’t preclude it as a habitable planet. 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-452 is a G2V type star, same as Sun, with almost same temperature and mass, just 20% more brighter. 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. Kepler-442b is about one-third larger than Earth, and the likelihood of it being rocky is around 60 per cent. Qualities of Kepler-442b matching the superhabitable criteria include: Kepler-442b doesn't meet all of the criteria: Additionally, some details are currently unknown: In 2009, NASA's Kepler spacecraft was completing observing stars on its photometer, the instrument it uses to detect transit events, in which a planet crosses in front of and dims its host star for a brief and roughly regular period of time. The source code for the WIKI 2 extension is being checked by specialists of the Mozilla Foundation, Google, and Apple. The ideal. A Kepler-442b (más néven KOI-4742,01) egy valószínűleg sziklás, Föld méretű exobolyg ó, ami a lakható övezetben kering a Kepler-442 nevű csillag körül a Földtől 1206 fényévre a Lant csillagképben. The duration of this period is inversely linked to the size of the star. 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. [1], The star Kepler-442 is a K-type main-sequence star with a mass of 0.61 solar masses, a radius of 0.59 solar radii and surface temperature of 4129 °C. Astronomie-Fans träumen bereits von Reisen zu dem "Erd-Cousin". Kepler-442b's axial tilt (obliquity) is likely very small, in which case it would not have tilt-induced seasons as Earth and Mars do.
