If and when an exoplanet “transits” or crosses in front of its host star, it blocks some of the star’s light. The telescope carries only one scientific instrument: a “photometer”, which simply measures the amount of light coming from those stars.

#Kepler telescope Patch

This patch of the sky is 115 square degrees, or roughly 575 times the apparent size of the full Moon on the sky.

The Kepler space telescope’s original mission was to observe one patch of the sky containing roughly 150,000 main sequence stars - stars like the Sun in the prime of their life. Astronomers from the Center for Astrophysics | Harvard & Smithsonian were responsible for the preparation of the catalog for potentially interesting stars, and have participated extensively in follow-up observations of Kepler planetary discoveries. The mission finally ended in 2018, though the data it produced continues to provide astronomers with valuable information about planets in our galactic neighborhood. After the spacecraft’s pointing control failed, the mission was renamed K2, and it continued to hunt for exoplanets as it tumbled slowly, with its field of view drifting slowly across the sky. Until it lost its ability to point, Kepler observed a region of the sky containing about 150,000 stars with potential planets, monitoring them for the slight decrease in light caused by planets crossing in front of the star. Most of those identifications have come thanks to one observatory: NASA’s Kepler space telescope.

Kepler's data is available free online, and you can use it to identify stars with exoplanets and calculate the basic parameters for the exoplanets (orbital characteristics, size). During its over nine and a half years of service, Kepler observed 530,506 stars and detected 2,662 planets. Only planets whose orbits are seen edge-on from Earth can be detected. These data are transmitted to Earth, then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star. After nine years of operation, the telescope's reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018.ĭesigned to survey a portion of Earth's region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and estimate how many of the billions of stars in the Milky Way have such planets, Kepler's sole scientific instrument is a photometer that continually monitored the brightness of approximately 150,000 main sequence stars in a fixed field of view. The principal investigator was William J. Named after astronomer Johannes Kepler, the spacecraft was launched on March 7, 2009, into an Earth-trailing heliocentric orbit. The Kepler space telescope is a retired space telescope launched by NASA to discover Earth-size planets orbiting other stars.
