Using Data Collected By NASA’s Kepler Space Telescope, Astronomers Discovered Seventeen New Extrasolar Planets

Using data collected by NASA’s Kepler space telescope, astronomers discovered seventeen new extrasolar planets.


Using data collected by NASA’s Kepler space telescope, a team of astronomers in Canada discovered 17 new exoplanets, including an Earth-sized globe. Named KIC 7340288b, the planet is rocky and is in the habitable zone of its mother star.


The sizes of 17 new planet candidates compared to Mars, Earth and Neptune. The green planet is KIC 7340288b. “KIC 7340288B is about 1,000 light years away, so we will never get there,” said Michelle Kunimoto, Ph.D. Candidate at the University of British Columbia.


But this is a really exciting discovery, since there are only 15 small and confirmed planets in the habitable zone found in Kepler’s data. This planet is only 1.6 times larger than Earth.


It orbits its host star once every 142.5 days at a distance of 0.444 AU (larger than the orbit of Mercury in the solar system) and receives approximately one third of the light that Earth receives from the Sun.


The smallest of the other 16 new planets discovered is only two-thirds the size of the Earth, and Kepler is one of the smallest planets ever found. The rest of the range is up to 8 times the size of the Earth.


In the study, Kunimoto and his colleagues presented the NRC Herzberg Astronomy and Astrophysics and Dr. Jaymie Matthews of the British Columbia professor. Henry Ngo used the transit method to see planets among the approximately 200,000 stars observed by the Kepler mission.


“Every time a planet passes in front of a star, it blocks a part of that star’s light and causes a temporary decrease in the brightness of the star,” he said. By finding these dives known as transits, you can find information about the planet, such as its size and how long it orbits it.


The astronomers also used the near infrared spectrometer (NIRI) imager and spectrometer in the Gemini North 8-Me telescope in Hawaii to capture tracking images of some stars that host planets.


“We took images of stars from space, such as the use of adaptive optics,” Kunimoto said. We can determine if there was a star nearby that could affect Kepler’s measurements, such as the cause of the sinking.


In addition to the new planets, the team was able to observe thousands of known Kepler planets using the transit method, and the census of the exoplanet as a whole would be re-analyzed.


“We must estimate how many planets are expected for stars with different temperatures,” Professor Matthews said.


“A particularly important result would be a planetary incidence rate of the habitable zone on Earth. How many planets are there like Earth? Stay.”
