Move over , Thelma and Louise ! Make mode , Bonnie and Clyde ! There ’s a newfangled couple of runaway knave in township . astronomer have discoveredthat a rogue major planet , part of the TW Hydrae group of stars , is really two planets orbiting each other .

The objects are known as 2MASS J11193254 - 1137466AB and they are about 3.7 times the mass of Jupiter each . It ’s difficult to put them in a box . They are too pocket-sized to be a conventional brown dwarf and they are not precisely planets , although they have the correct muckle . That ’s why they are also call rogue planets   –   they are planetal mass objects without a genius . This system of rules is   the low - mass , free - floating binary ever observed .

The object were   first discovered last class and are   believed to be associated with the TW Hydrae radical . In a newspaper published in theAstrophysical Journal Letters , the investigator cater   an 80 per centum chance that the rogue planet formed with the residue of the TW Hydrae affiliation .

We are good at work out the properties of normal whiz than unusual and utmost object like the binary planet . We recognize that TW Hydrae form about 10 million eld ago and that the latest estimate for its distance is   about 160 calorie-free - years from Earth .

That datum also applies to the rogue planets , but free-base on the aloofness and apparent separation , stargazer have work out that they are about 583 million kilometers ( 362 million miles ) from each other . That ’s almost four times the distance between the Sun and the Earth .

These two object have been described as lying on a “ link of astronomic ” interest , being on a   cross - category of space objects . They are probably made of the same stuff of chocolate-brown nanus and yet are so small that their prop are closer to exoplanets . Studying them might actually give us more penetration into   how gas heavyweight planet form and carry . It ’s often difficult to study them because of the promising igniter of their legion star , which is not an issue for our pair of rogue physical object .

2MASS J11193254 - 1137466AB will certainly receive a draw more attention now that its binary status has been detected . There ’s lot that we can memorise from these two runaway objects .
