How many exoplanets has Kepler found?
2,662 exoplanets
Kepler observed 530,506 stars and discovered 2,662 exoplanets over its lifetime.
What planets did Kepler find?
Kepler-20e and Kepler-20f were the first Earth-size planets to be found (their radii are 0.87 and 1.03 times the radius of Earth, respectively). Kepler-9b and Kepler-9c were the first two planets observed transiting the same star. Kepler-186f was the first Earth-size planet found within the habitable zone of its star.
Is Kepler 22b a exoplanet?
The discovery of Kepler-22b, an exoplanet orbiting Kepler-22 (otherwise known as UCAC3 276-148830, a sun-like G5 star about 600 light years from Earth) within the “habitable zone,” the region where liquid water could exist on a planet’s surface, was confirmed on December 5, 2011.
What are the 4 types of exoplanets?
So far scientists have categorized exoplanets into the following types: Gas giant, Neptunian, super-Earth and terrestrial.

How many planets has Kepler discovered?
NASA’s Kepler spacecraft has discovered 170 planetary systems containing between two and six transiting planets.
What is Kepler space probe?
Kepler was a space telescope designed to survey a portion of the Milky Way galaxy in search of exoplanets, which are planets outside our solar system. Using data from the Kepler mission and the extended K2 mission, scientists have identified more than 2,800 candidate exoplanets and have confirmed more than 2,600 of these as bona fide planets.
What is planet Kepler?
Kepler-22b is an extrasolar planet orbiting (going around) G-type star Kepler-22. It is located about 600 light years away from Earth in the constellation Cygnus . It was found by NASA ‘s Kepler Space Telescope. It is also the first known planet to orbit within the habitable zone of a Sun-like star.
What is the orbit of the Kepler telescope?
Kepler’s Orbit. Kepler does not orbit the Earth, rather it orbits the Sun in concert with the Earth, slowly drifting away from Earth. Every 61 Earth years, Kepler and Earth will pass by each other. Throughout the lifetime of the mission, Kepler will point at just one place on the sky in the Cygnus-Lyra constellations.
