Students have found 17 new planets. Some of them are similar to Earth

A student of the astronomical Department of the University of British Columbia Michelle Kunimoto opened 17 new exoplanets, including potentially habitable planet the size of Earth, according to the portal . After studying the data collected by the mission for NASA «Kepler» during his initial four-year program, the researcher found traces of previously undetected objects in places located in the so-called “Goldilocks zone” where liquid water could exist on the surface of a rocky planet.
Scientists have found a new extrasolar planets
The New findings, which were published in the Astronomical journal, offers one of the most rare planets in the Universe. Officially named KIC-7340288 b , discovered thanks to the efforts of Michelle Kunimoto, just one and a half times bigger than Earth. As is known, these measurements indicate the presence of extrasolar planets solid and not gaseous surface. In addition, the detected object is located in the habitable zone of their stars, significantly increases the chances of detection on the planet of organic life in the future.
Whatever it was, she Kunimoto, candidate of physical and astronomical Sciences, is configured not so optimistic. According to her opinion, because of the huge distance that separates us from the unique finds, we could get in the neighborhood of its stars only a few hundred thousand years and only in the case if we finally managed to tame the speed of light.
A Year on earth-like the planet is about 142 days, which is 0,444 astronomical units (0,444 or the distance between the Earth and the Sun). This characteristic somewhat brings it closer to mercury from the Solar system, however due to the fact that the parent star, the planet is slightly smaller compared to our sun, receives only about one third of all light that the Earth receives from the Sun. The presence of these properties makes the object KIC-7340288 b is really an incredible find, because so far in the habitable zone was found only 15 confirmed planets officially opened according to the telescope “Kepler”.
KIC-7340288 b may be similar to the Earth in a number of key parameters
Of the remaining open 16 new planets, the smallest object has only two-thirds the size of the Earth, thus automatically becoming the champion among all the planets discovered by “Kepler” to the present time. The sizes of other exoplanets are within up to eight Earth diameters.
To search For all planets of Kunimoto used known to many transit method, which measures the number of the shaded light coming from the parent star to the observer. In order to find 17 new facilities, the academic had to analyze the data of over 200,000 stars observed by the mission, the famous “Kepler”.
Watching the transits of the planets causing a temporary reduction in the brightness of stars, Kunimoto received information about their sizes and time in which objects needed in order to make a complete revolution around its sun. Scientific supervisor of student, Professor Jamie Matthews, said that his client carried out the study may shed light on the frequency of earth-like objects in the habitable zone of other stars, thus prompting scientists possible location of undiscovered humanity , some of which may be of great interest to modern science
