That is, gas giant planets that would circle their stars on Jupiter-like orbits of 3 to 5 astronomical units (AU), or Earth-Sun distances. Our own Jupiter lies at 5.2 AU, which means it orbits our Sun roughly once every 12 years.<\/p>\n<p><a href=\"http:\/\/www.forbes.com\/sites\/brucedorminey\/2016\/01\/31\/solar-systems-like-ours-remain-scarce\/#135f34791d58\" target=\"_blank\">Read more<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Do we owe our existence to Jupiter?
