6 1 1 8 ▁b ▁is ▁a ▁brown ▁d war f ▁located ▁approximately ▁ 1 7 1 ▁light - year s ▁away ▁in ▁the ▁const ell ation ▁of ▁Ser p ens ▁Ca uda . ▁This ▁object ▁had ▁a ▁minimum ▁mass ▁of ▁ 1 1 . 9 ▁times ▁that ▁of ▁Jup iter . ▁Due ▁to ▁its ▁high ▁mass ▁the ▁planet ▁is ▁likely ▁to ▁be ▁very ▁hot ▁and ▁possibly ▁g low ing ▁faint ly . ▁The ▁lower ▁limit ▁on ▁its ▁mass ▁is ▁only ▁slightly ▁less ▁than ▁the ▁de uter ium ▁burning ▁threshold ▁that ▁some ▁astronom ers ▁use ▁to ▁distinguish ▁between ▁plan ets ▁and ▁brown ▁d war fs . ▁Depending ▁on ▁the ▁incl ination ▁of ▁its ▁orbit , ▁the ▁true ▁mass ▁could ▁be ▁above ▁this ▁limit . ▁The ▁orbit ▁of ▁the ▁object ▁is ▁located ▁at ▁the ▁average ▁distance ▁of ▁ 1 . 4 5 ▁astronom ical ▁units ▁from ▁the ▁parent ▁star , ▁taking ▁ 4 0 ▁months ▁to ▁complete ▁one ▁ecc ent ric ▁orbit . ▁ ▁On ▁November ▁ 2 5 , ▁ 2 0 0 9 , ▁its ▁incl ination ▁was ▁calculated ▁to ▁be ▁ 1 6 3 . 1 ° ▁and ▁its ▁true ▁mass ▁ 4 2 ▁times ▁that ▁of ▁Jup iter , ▁class ifying ▁this ▁as ▁a ▁brown ▁d war f . ▁ ▁References ▁ ▁External ▁links ▁▁▁▁▁▁ ▁Category : B rown ▁d war fs ▁Category : Ser p ens ▁( const ell ation ) <0x0A> </s> ▁As car is ▁lum br ico ides ▁is ▁the ▁" large ▁round w orm " ▁of
