The Kepler orrery is a group of animations created by Daniel Fabrycky and Ethan Kruse, which show exoplanets and stars discovered by the Kepler Space Telescope. 1,815 exoplanets and 726 planetary systems are in the animation.
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
The star is colder and smaller than the Sun, having a temperature of 3,457 K (3,184 °C; 5,763 °F) and a radius 45% of the Sun's, [6] and is not visible to the naked eye. [7] The star is 2.4 ± 0.6 billion years old [ 8 ] and displays moderate stellar activity , but whether it has star spots , [ 9 ] which would tend to create false signals [ a ...
Scientists analyzed famed astronomer Johannes Kepler’s 1607 sketches of sunspots to solve a mystery about the sun’s solar cycle that has persisted for centuries.
On December 20, 2011, the Kepler team announced the discovery of the first Earth-size exoplanets, Kepler-20e [154] and Kepler-20f, [155] orbiting a Sun-like star, Kepler-20. [ 164 ] Based on Kepler's findings, astronomer Seth Shostak estimated in 2011 that "within a thousand light-years of Earth", there are "at least 30,000" habitable planets ...

Kepler-4 is a G0-type star, which is similar to the Sun, except slightly brighter. The star is 1.117 M sun and 1.555 R sun , or 111% the mass of and 155% the radius of the Sun. [ 5 ] With a metallicity of .09 (± 0.10) [Fe/H], Kepler-4 is more metal-rich than the Sun, a figure that is important in that metal-rich stars tend to have orbiting ...
It was discovered by NASA's Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet's surface. [4] Kepler-22 is too dim to be seen with the naked eye. Kepler-22b's radius is roughly twice that of Earth. [5]
