The results were announced at the AAS meeting in 2015. I use WIKI 2 every day and almost forgot how the original Wikipedia looks like. Obilježja. Kepler-442b is a near-Earth-sized exoplanet with a radius 1.34 times that of Earth. ESI Rating –.84. A year on Kepler 452b is only 21 days longer than a year on Earth. Both Kepler-438b and Kepler-442b orbit red dwarf stars that are smaller and cooler than our sun. This is reflected in its orbital distance, just outside of the point where the tidal interactions from its star would be strong enough to tidally lock it. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. [12] For comparison, the Solar System is 4.5 billion years old. 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. Kepler-442b là một ngoại hành tinh, có khả năng là một hành tinh đất đá, quay xung quanh trong vùng có thể sống được của một sao lùn cam Kepler-442, cách Trái Đất khoảng 1.206 năm ánh sáng (370 parsec) chòm sao Thiên Cầm. Mérete 1,34 földméret és tömege 2,34 földtömeg (egy életképes bolygó a föld méretének 1,3-szorosa és 2 földtömeg lenne.) This is somewhere between a red dwarf star and a yellow star, like our sun. [3] It has a radius of 1.34 R⊕. 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. NASA’s Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system, and to date has offered scientists an assortment of more than 4,000 candidate planets for further study -- … Would you like Wikipedia to always look as professional and up-to-date? 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. [7] K-type main-sequence stars are smaller than the Sun and live longer, remaining on the main sequence 15 to 30 billion years compared to the Sun's estimated 10 billion. 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. 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. 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 the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. AP Physics Planet Project. [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-22's star is a bit smaller than our sun, so its habitable zone is slightly closer in. Kepler-442b may have oceans. 3. Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. What would Exoplanet Kepler 442b look like? The duration of this period is inversely linked to the size of the star. Kepler 442b is known to be one of the planets of all planetary. 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. Kepler-442b is about one-third larger than Earth, and the likelihood of it being rocky is around 60 per cent. Kepler-452 is the name of a star in the constellation of Cygnus (the swan). [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. [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.
