Kepler-442 b; Alternative planet names : KOI-4742.01, KOI-4742 b, KIC 4138008 b, Gaia DR2 2100258047339711488 b: Description: This planet has been discovered by the Kepler spacecraft. 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). [12] Despite these properties, the small M-type and K-type stars can pose a threat to life. Approximate size comparison of Kepler-442b with. It receives 1.4 times our solar flux. An artist’s impression of Kepler-442b. It was described as being one of the most Earth-like planets, in terms of size and temperature, yet found. It is 1.5 billion years older than the Sun. These stars are not only smaller but also cooler when compared to the sun. [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. 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. Kepler-442b may have oceans. NASA announced the confirmation of the exoplanet on 6 January 2015. Looking at the star of Kepler 438 B with a naked eye is almost unclear. 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.

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. 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. 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. As of July, 2018, Kepler-442b was considered the most-habitable non-tidally locked exoplanet discovered. 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.) Planets similar to or like Kepler-442b. 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. Kepler-442, stellar object 1.1. This planet was revealed to be located in its habitable zone. Kepler-442b, 1,100 light-years away, is 33 percent bigger than Earth and orbits its star once every 112 days. And it is gets the Earth from the sun. Both Kepler-442b and Kepler-438b, orbit red dwarf stars. 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. 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. Its orbit is probably close to circular (eccentricity 0.04) so it will also lack eccentricity-induced seasonal changes like those of Mars. The discovery, along with the notable planetary systems of the stars Kepler-438 and Kepler-440, were announced on 6 January 2015.[1]. 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 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. The age of the planetary system is unknown, but most estimates are between 2.7 billion years and 8.1 billion years. 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. You could also do it yourself at any point in time. Kepler 442b (ESI=0.84) is a planet 1.3 times the size of Earth discovered in 2015. [8] Despite these properties, the small M-type and K-type stars can pose a threat to life. 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. The star's apparent magnitude, or how bright it appears from Earth's perspective, is 14.76. Kepler 438B has resulted in radiation in large quantities from its wire. 442b orbits an orange star. By K.G Orphanides. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another “Earth.” 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. Kepler-442 b, planet, semi-major axis: 0.41 +0.06 −0.21 AU. Both Kepler-438b and Kepler-442b orbit red dwarf stars that are smaller and cooler than our sun. The results are presented in a paper accepted by the Astrophysical Journal. 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. This planet was revealed to be located in its habitable zone. 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'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. [13] 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. 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. Both Kepler-438b and Kepler-442b orbit red dwarf stars that are smaller and cooler than our sun. [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. 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. How many stars like our sun host planets like our Earth? ESI Rating –.84.
