You ’re reckon at an artist ’s conception of GJ 504b , the lowest - quite a little planet ever detected around a star using direct imaging techniques . Located 57 light - twelvemonth away , it ’s about four times the mass of Jupiter . And it ’s pink . Really , really pinkish .

The freshly discovered planet orbits around star GJ 504 , a sun that ’s very similar to our own , and one that can be seen by the naked eye in the constellation Virgo .
The pink satellite , or a color that NASA scientist Michael McElwain describes as being “ redolent of a dark cerise blossom , a dull magenta , ” manipulate at a temperature of about 460 degrees Fahrenheit ( 237 Celsius ) and orbits at a aloofness of 43.5 AU from its star ( 1 AU = middling distance of Earth to the Sun ) .
This means that GJ 504b is site tops - recondite in its outer solar system . For perspective , Jupiter revolve at 5 AU , Saturn at 9 AU , and Neptune at about 30 AU .
The major planet was project by using infrared data pulled from the Subaru Telescope in Hawaii .
The striking coloring of the gas whale is suggestive of its youth ; it ’s just a baby . NASA scientist estimate the eld of the solar system at a mere 160 million years . The planet is literally shine from the heat of its recent formation .
And give the planet ’s extreme distance from its sun , it ’s changing our excogitation of how giant planets form . The going hypothesis is the core group - accumulation simulation where Jupiter - like satellite take shape in the gas - rich debris magnetic disk that surrounds a unseasoned whiz . This model is all fine - and - well for planet close than 30 AU , but it proves problematic for worlds located further from their adept .

“ This is among the hardest satellite to explain in a traditional planet - formation fabric , ” said Markus Janson through a freeing . He ’s a Hubble postdoctoral fellow at Princeton University in New Jersey . “ Its discovery implies that we need to earnestly weigh alternative formation theories , or perhaps to reassess some of the basic assumptions in the kernel - accumulation theory . ”
These outcome are set to look in an upcoming edition of The Astrophysical Journal .
