In what seem to be a record , two unlike teams of astronomers have confirmed the existence of a 7th planet revolve a dwarf asterisk 2,500 light - years out . And incredibly , all seven planets are catch in a tight orbit closer than the Earth ’s distance to the Sun .
The solar scheme in question is hollo KIC 11442793 , and it was antecedently known to host three planets . A new newspaper , which is set to be peer reviewed in the Astrophysical Journal , describes the other four , let in the lately discovered seventh planet . The other squad to detect the seventh planet consists of unpaid worker using thePlanet Hunters Website .
The uncovering were made with Kepler data and by using the transit method .
Interestingly , the solar system of rules intimately resembles our own , despite it being so heavyset . It ’s got five terrestrials planets on the interior ( including two super - Earths ) and two gas giants on the outside . The outermost planet is an orbit of 1 AU ( the distance of the Earth to the Sun ) .
The newly discovered planet , which is 2.8 times the sizing of Earth , is the fifth out with an eye socket of 125 years .
There is another candidate for most crowded solar organization , however : HD 10180.Some astronomers take it has nine planet . There ’s also GJ 997C , which might also have seven planet .
Read both newspaper at the preprint server , arXiv : “ The Planetary System to KIC 11442793 : A Compact Analogue to the Solar System . ” & “ Planet Hunters VI : The First Kepler Seven Planet Candidate System and 13 Other Planet Candidates from the Kepler Archival Data . ”
