Strange Milky Way planetary system leaves scientists puzzled

WASHINGTON, July 22 : Scientists are documenting a planetary system in the Milky Way galaxy that is so starkly dissimilar to our own solar system that they are struggling to find the proper terminology to describe it.The system includes a red dwarf star about 40 per cent of the mass of our sun that is orbited by a brown dwarf, a celestial body that blurs the line between planet and star.

But the object that orbits the brown dwar
