article_snippet: The findings are based on data from the American space agency Nasa's Kepler space telescope, which has confirmed the existence of around 1,000 planets orbiting stars in the Milky Way.
article_snippet: Many of the stars have solar systems of two to six planets, but scientists believe there could be more that remain undiscovered by Kepler, which is best suited to finding large planets in relatively close orbits.
article_snippet: 124 planetary systems in the survey – based on data from the Kepler satellite, fit with this formula .
article_snippet: You can also calculate if a planet is 'missing' in the sequence.
article_snippet: You can also calculate if a planet is missing in the sequence. '
article_snippet: We decided to use this method to calculate the potential planetary positions in 151 planetary systems, where the Kepler satellite had found between three and six planets,' said Mr Jacobsen. '
article_snippet: But We only made calculations for planets where there is a good chance that you can see more planets with the Kepler satellite.'
article_snippet: In this way, more planets predicted a total of 228 planets in the planetary systems and concluded that each system should have an average of one to three planets in the habitable zone.
article_snippet: The scientists, whose findings appear in the journal Monthly Notices of the Royal Astronomical Society, have made a shortlist of 77 'hidden' planets.
article_snippet: The scientists, whose findings appear in the journal Monthly Notices of the Royal Astronomical Society say 77 'hidden' planets have a good chance of being spotted as The scientists, whose findings appear in the journal Monthly Notices of the Royal Astronomical Society pass in front of The scientists, whose findings appear in the journal Monthly Notices of the Royal Astronomical Society parent stars .
