The idea is that the Sun\u2019s original birth cluster of at least a 1000 stars was pretty crowded and there was ample opportunity to gravitationally strip a planet from a stellar brother or sister. But guess stars don\u2019t get jealous, eh?<\/p>\n<hr>\n<p>A possible super-earth lying on our solar system\u2019s outer fringes may have been captured from a star in our Sun\u2019s original stellar birth cluster, Alexander James Mustill, an astronomer at Lund University in Sweden, tells me.<\/p>\n<p>Even though Planet 9\u2019s existence still remains up for debate, a growing body of evidence for nearly decade now indicates the presence of a planet some 10 times the mass of Earth that orbits the Sun at a distance of up to 900 astronomical units (or Earth-Sun distances).<\/p>\n<p>Mustill says that depending on how long the Sun stayed in proximity with its stellar siblings, indeed, Planet 9 may have been captured within the first 100 million years of our star\u2019s formation. As Mustill notes, evidence suggests that the Sun was born into a large open cluster of at least a thousand stars.<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.forbes.com\/sites\/brucedorminey\/2016\/03\/30\/planet-9-may-hail-from-suns-stellar-birth-cluster\/#3c87c4d8462c\">http:\/\/www.forbes.com\/sites\/brucedorminey\/2016\/03\/30\/planet-...87c4d8462c<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Planet 9, if indeed it\u2019s out there, may have been stripped from one of our Sun\u2019s stellar siblings, very early in the life of our solar system.
