Two of the discoveries announced, Kepler-438b and Kepler-442b, are especially intriguing, as they are the most comparable to the Earth size-wise of any exoplanets yet discovered. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. The distance from Earth from Kepler 440b to 851.3 light years is far away. If the R.A. is positive then its eastwards. Kepler-442b extrasolar planet ... Discoverer or inventor: Kepler; Time of discovery or invention: 2015; Distance from Earth: 1,120 ±1 ly; Right ascension 285.3665595681 degree Declination 39.280062113497 degree: Authority control This is only an … It is located 1,206 light years away from Earth, residing in the constellation Lyra. For Kepler-442, the location is … Its orbital distance (0.7 AU), size (1.41x larger than Earth) and mass (at least 2.8x higher than Earth) means that it’s a rocky planet and could sustain a global ocean. Kepler-440b Earth has 1.86 times the radius. Kepler-442b (KOI-4742.01) is a confirmed exoplanet orbiting within the habitable zone of its star (Kepler-442). NASA.gov brings you the latest images, videos and news from America's space agency. Kepler-440b is stable in the habitable zone and its region where liquid water may exist on the surface of the planet. The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). 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. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. 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). Pluto Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter Kepler-442 b Habitable zone. Kepler-22b is slightly larger than Earth, but has an orbit that is pretty similar (290 days to Earth's 365). Kepler says the … Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. Kepler 442b is the main successive star of K-Type, in which that is predicts that there is a set of 0.61 solar masses Kepler-442b is a super-earth orbiting a K-type star with a radius 1.34x larger than Earth's and a mass estimated at 2.34x of Earth Kepler-440b super-earth exoplanet. Kepler 442b receives about 70% of the sunshine from sunlight.
