About 2 light-years away is Kepler-90: Star with Planetary System that is set up lot like ours. Information about System comes from observations by Kepler Space Telescope. Discovery of seventh Planet was made by citizen scientists using Zooniverses Planet Hunter and was published in Arxiv. Org. Other details of system were published by lead author Juan Cabrera of DLR Institute of Planetary Research in Astrophysical Journal. Kepler-90 is main sequence Star has at least planets orbiting it, more than any other discovered system. It is set up much like ours, with rocky ones closer to Star and much larger gas planets around exterior of system. Distinct difference between Kepler-90 and our System is planetary orbits are much more compact than ours. Innermost Planet, Kepler-90b, has period of only 7 Earth days. As comparison, Mercury takes 88 to travel Around sun. Outermost Planet, Kepler-90h is about one away from its Star. This means that entire system would fit inside of Earth's orbit. All of planets have smaller radii than Neptune. Other planets have relatively tight orbits as well. Rest Of Planets Have Orbits That Take 9 60 92 125 211, And 331 Days Respectively. However, orbital periods are precise. There are 25. 7 hour variation, is larger than any other planetary system discover. This could be because there are actually more than we have confirm. Also, because planets are so close to host Star, fluctuations in gravitational pull could also be affecting orbital periods. Despite any possible gravitational fluctuations, system is believed be very stable. Many astronomers may be able to use this Planetary setup to learn more about Planetary formation and also about what makes stable system. European Space Agency Is Deliberating On Mission Called Planetary Transits And Oscillations Of Stars Which Would Allow For More In-depth Analysis Of Exoplanets Orbiting Bright Stars. It could also potentially provide information about atmosphere of exoplanets and determine if there is possibility of alien life. ESA is expected to make decision about mission within next few months. Tour of Seven-Planet System Around Star Kepler-90 from Robert on Vimeo.

Nomenclature and history

Prior to Kepler observation, had 2MASS catalogue number 2MASS J18574403 + 4918185. It has designation of KIC 11442793 in Kepler Input Catalog, and give Kepler object of interest number of KOI-351 when it was found to have transiting planet candidate. Star's Planetary Companion Was Discovered By NASA's Kepler Mission, Mission Tasked With Discovering Planets In Transit Around Their Stars. Transit Method That Kepler Uses Involves Detecting Dips In Brightness In Stars. These dips in brightness can be interpreted as planets whose orbits move in front of their stars from perspective of Earth. Name Kepler-90 Derives Directly From Fact That Star Is Catalogue Of 90 Stars Discovered By Kepler To Have Confirmed Planets. Designation b, c, e, f, g, h, and i derives from order of discovery. Designation Of B Is Given To First Planet Orbiting Give Star, Followed By Other Lowercase Letters Of Alphabet. In case of Kepler-90, there are eight planets discover, so designations up to i are used.
