It has a temperature of 4402 K and is around 2.9 billion years old, with some uncertainty. The discovery, along with the notable planetary systems of the stars Kepler-438 and Kepler-440, were announced on 6 January 2015.[1]. It has an equilibrium temperature of 233 K (−40 °F). The planet orbits a (K-type) star named Kepler-442. Werbefrei streamen oder als CD und MP3 kaufen bei Amazon.de. This planet was revealed to be located in its habitable zone. Stars that Kepler 452b orbits its star know whether the planet, Kepler-438b, has a field. Obilježja. Kepler-442b[1][4][5] (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[6] Kepler-442, about 1,206 light-years (370 parsecs), from Earth in the constellation Lyra. Around 1120 lightyears away, Kepler-442b is a planet 1.3 times the size of the Earth. Additionally the Square Kilometer Array would significantly improve radio observations over the Arecibo Observatory and Green Bank Telescope. Kepler-438b, 475 light-years away, is 12 percent bigger than Earth and orbits its star once every 35.2 days. Therefore, it is too dim to be seen with the naked eye. Also, according to an index developed in 2015, Kepler-442b is even more habitable than Earth. Kepler-442b is also the most similar known case of a superhabitable planet. In this last test, Kepler observed 50000 stars in the Kepler Input Catalog, including Kepler-442; the preliminary light curves were sent to the Kepler science team for analysis, who chose obvious planetary companions from the bunch for follow-up at observatories. The mass of the exoplanet is estimated to be 2.36 M⊕. Going to this index, Earth has a rating of 0.829, but Kepler-442b has a rating of 0.836. The planet orbits a star named Kepler-442. Because it is closer to its star than Earth is to the Sun, the planet will probably rotate much more slowly than Earth; its day could be weeks or months long (see Tidal effects on rotation rate, axial tilt, and orbit). Kepler-442b (KOI-4742.01) is a confirmed exoplanet orbiting within the habitable zone of its star (Kepler-442). Kepler 442b is known to be one of the planets of all planetary. Kepler-442b orbits its host star with an orbital period of 112 days, 9 hours, 10 minutes, and 24 seconds, and has an orbital radius of about 0.4 times that of Earth's (a little larger than the distance of Mercury from the Sun, which is about 0.38 AU). The ideal, This page was last edited on 29 December 2020, at 06:51. It has a radius of 1.34 R⊕. It orbits on the inner edge of the habitable zone of a red dwarf, Kepler-438, about 472.9 light-years (141,8 parsecs) from Earth in the constellation Lyra. The Kepler spacecraft focused on a single small region of the sky but next-generation planet-hunting space telescopes, such as TESS and CHEOPS, will examine nearby stars throughout the sky. [4][5] 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. [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. Udaljen je 1206 svjetlosnih godina. By K.G Orphanides. By K.G Orphanides. 07 Oct 2015. Kepler-442b, 1,100 light-years away, is 33 percent bigger than Earth and orbits its star once every 112 days. Juli 2015 öffentlich bekannt gegeben. It orbits a K-type star, which is a type of star similar to the Sun, but with a longer expected lifetime. Kepler-442B Liam Mott. It is estimated to have a mass of 2.34 Earth masses. [1] Its luminosity (L☉) is 11% that of the Sun. The planet orbits the K-type starKepler-442 once every 112.3 days. [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]. One review essay in 2015 concluded that Kepler-442b, along with the exoplanets Kepler-186f and Kepler-62f, were likely the best candidates for being potentially habitable planets.[15]. A superhabitable planet would have shallow oceans. Kepler-62f has several qualities that make it likely to host life. Kepler 442b receives about 70% of the sunshine from sunlight. 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. [2] Its orbit is probably close to circular (eccentricity 0.04) so it will also lack eccentricity-induced seasonal changes like those of Mars. [12] Despite these properties, the small M-type and K-type stars can pose a threat to life. This planet was revealed to be located in its habitable zone. The surface gravity on Kepler-442b would be 30% stronger than that of Earth, assuming a rocky composition similar to that of Earth. Gibt es auf Kepler-452b Lebewesen, Wasser, Elektrizität? 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. Entdecken Sie Kepler-452b Orbit von Sayer bei Amazon Music. Uz njega su još objavljeni i planeti Kepler-440b i Kepler-438b. Solche Fragen erinnern schon sehr an Science Fiction Filme, doch auch die Wissenschaftler der NASA sind von der Entdeckung des erdähnlichen Planeten begeistert und ganz aus dem Häuschen. It is thought that the force of gravity on Kepler 452b would be twice as strong as Earth's gravity. Because of its radius, it is likely to be a rocky planet with a solid surface. The habitable zone is a region around a star where temperatures are right for water—an essential ingredient for life as we know it—to pool on the surface. The scientists give it a 97 percent chance of being in the habitable z… Kepler-452b is the first planet orbiting a star about the same size and temperature as the sun. Calum Brook Nicolson Kepler-442b ℗ 1112623 Records DK Released on: 2019-11-13 Auto-generated by YouTube. It is located 1,206 light years away from Earth, residing in the constellation Lyra. 25:05 . Host star. 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.

Both Kepler-438b and Kepler-442b orbit red dwarf stars that are smaller and cooler than our sun.Kepler-438b circles its star every 35 days and receives about 40 percent more light than Earth; it's estimated to have a 70 percent chance of being in the habitable zone of its star.Kepler-442b completes one orbit every 112 days and gets about two-thirds as much light as Earth. Loading... Unsubscribe from Liam Mott? Kepler-62f. Kepler-442, stellar object 1.1. Its discovery was announced in 2015. The star has a mass of 0.61 M ☉ and a radius of 0.60 R ☉. Bei der Bekanntgabe seiner Entdeckung wurde Kepler-442b als einer der am meisten erdähnlichen Planeten bezeichnet, in Bezug auf seine Größe und Temperatur, die bis dahin gefunden worden sind.[2][3]. Die NASA gab die Bestätigung des Exoplaneten am 6. 1. Observations for the potential exoplanet candidates took place between 13 May 2009 and 17 March 2012. The star's apparent magnitude, or how bright it appears from Earth's perspective, is 14.76. The duration of this period is inversely linked to the size of the star. [16] This is uncertain because Kepler-442b's atmosphere and surface are unknown, but this would be possible. Kepler-452b ist ein Exoplanetenkandidat des Sterns Kepler-452, der vom Weltraumteleskop „Kepler“ identifiziert wurde. [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. And it is gets the Earth from the sun. [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.
