Kepler 438B produces more powerful stars than the Sun. Calum Brook Nicolson Kepler-442b ℗ 1112623 Records DK Released on: 2019-11-13 Auto-generated by YouTube. 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). It is 1.5 billion years older than the Sun.

Kepler-442b, 1,100 light-years away, is 33 percent bigger than Earth and orbits its star once every 112 days. Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. NASA.gov brings you the latest images, videos and news from America's space agency. It was identified by the Kepler space telescope, and its discovery was announced by NASA on 23 July 2015. Would you like Wikipedia to always look as professional and up-to-date? AP Physics Planet Project. 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. Kepler orbits closer to its star than Earth does to the Sun: its year is only 112.30 days long (this is one value we know very accurately.) Die Entdeckung des Exoplaneten Kepler-452b begeistert nicht nur Forscher. Around 1120 lightyears away, Kepler-442b is a planet 1.3 times the size of the Earth. By K.G Orphanides. 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. On January 6, 2015, along with the notable stars of Kepler-438 and Kepler-440, it was announced that the star has an extrasolar planet (a super-Earth) orbiting within the habitable zone, named Kepler-442b. These stars are fainter and cooler than our Sun, and 7.5% to 50% as massive. 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. Otkriven je i potvrđen 6. siječnja 2015., i to tranzitom. [1][2] It is estimated to have a mass of 2.34 Earth masses. Feiten. AP Physics Planet Project. Additionally the Square Kilometer Array would significantly improve radio observations over the Arecibo Observatory and Green Bank Telescope.[17]. Kepler-442b may have oceans. Kepler-442, stellar object 1.1. 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. Udaljen je 1206 svjetlosnih godina. It has a temperature of 4402 K and is around 2.9 billion years old, with some uncertainty. Kepler 442b (ESI=0.84) is a planet 1.3 times the size of Earth discovered in 2015. Kepler 442b is known to be one of the planets of all planetary. As of July, 2018, Kepler-442b was considered the most-habitable non-tidally locked exoplanet discovered. Kepler-442 is a K-type main-sequence star approximately 1,206 light years from Earth in the constellation Lyra. This page was last modified on 8 May 2016, at 18:05. Of these 20 candidates, nine have been previously investigated and determined to be verified planets, including notables like Kepler-62f, Kepler-186f, Kepler-283c, Kepler-296f and Kepler-442b. [3] It has a radius of 1.34 R⊕. Kepler-442b. 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. According to the parameters, this planet has 70 percent chances of being in the habitable zone of its star. Also, according to an index developed in 2015, Kepler-442b is even more habitable than Earth. Congratulations on this excellent venture… what a great idea! 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. 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. The star that Kepler 452b orbits is very similar to our sun. Kepler orbits closer to its star than Earth does to the Sun: its year is only 112.30 days long (this is one value we know very accurately.) Kepler-22's star is a bit smaller than our sun, so its habitable zone is slightly closer in. A new … It orbits Kepler-442 in 112 days. Wednesday 7 October 2015. 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. ‹ Back to list. 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. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. [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. [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. 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. Obilježja. [8] Despite these properties, the small M-type and K-type stars can pose a threat to life. Kepler-442b (Rocky Planet) : The Size Of Exoplanet With Earth The results were announced at the AAS meeting in 2015. This list shows all planetary and stellar components in the system.
