Kepler-69b is the Kepler-69 system’s innermost planet. It’s most likely a super-Earth or a mini-Neptune. It is an exoplanet similar to Neptune that orbits a G-type star. It has a mass of 5.65 Earths, takes 13.7 days to complete one orbit of its star, and is located 0.094 AU away from it. It was discovered in 2013 and was announced at the time.
Kepler-69 b is an exoplanet that orbits the star Kepler-69, which is 2381.7 light-years (730.2 pc) from our Solar System. Its discovery was made public in 2013. Kepler-69, the host star, has an apparent brightness of 13.7 and an absolute magnitude of 4.4. It is 0.8 times more massive and 1.2 times larger than our Sun. The surface temperature is 5630 degrees Fahrenheit, and the spectral types are G4 V.
Kepler-69 is a star with a radius of 0.93 times that of the Sun and a mass of 0.81 times that of the Sun. It is 2382.98 light-years away from the solar system and is predicted to be 9.8 billion years old, as opposed to the Sun’s 4.6 billion years. Kepler-69 is known to be orbited by two exoplanets. The extrasolar planet Kepler-69 b orbits the star Kepler-69 every 13.7 days at an orbital distance of 0.09 AU in this planetary system.
Kepler-69 b is an extrasolar planet (exoplanet) that circles the star Kepler 69 in the constellation Cygnus. An exoplanet is a planet that circles a star other than the Sun. The planet’s orbital period, or year, is 13.722341 days, or 0.04 Earth Years. By the end of a full year, the Earth will have completed 26.60 orbits of its star.
The semi-major axis is the point in the orbit that is farthest from the star. The Earth orbits the Sun with a semi-major axis of little over 1 A.U. The average distance between the Earth and the Sun is one A.U. The planet travels closer to its star than Mercury does to the Sun.
There are five planets in the Kepler-62 system: 62b, 62c, 62d, 62e, and 62f. There are two planets in the Kepler-69 system: 69b and 69c. The super-Earth planets are Kepler-62e, 62f, and 69c. Two of the newly identified planets revolve around a star that is smaller and cooler than the Sun. Kepler-62f is only 40% the size of Earth, making it the nearest exoplanet to our planet known in another star’s habitable zone. Kepler-62f is most likely composed of stony material. Kepler-62e orbits on the outskirts of the habitable zone and is around 60% the size of Earth.
Kepler-69c, the third planet, is 70% larger than Earth and circles in the habitable zone of a star similar to our Sun. Kepler-69c’s composition is unknown, but its orbit of 242 days around a Sun-like star mimics that of our neighboring planet Venus.
The Kepler space telescope, which analyzes the brightness of over 150,000 stars simultaneously and continuously, is NASA’s first project capable of identifying Earth-sized planets surrounding stars like our Sun. Kepler-62e was the first of these habitable zone planets to be discovered, orbiting its star every 122 days.
