GJ 504b-lowest-mass exoplanet around a Sun-like star
Astronomers have spotted the lowest-mass planet ever detected around a Sun-like star in the constellation called Virgo. Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers imaged the giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.
This lowest-mass exoplanet GJ 504b lies at a projected distance of 43.5 AU from its star, the actual distance depends on how the system tips to our line of sight, which is not precisely known. It orbits the G0-type star GJ 504, which is slightly hotter than the Sun and is faintly visible to the unaided eye in the constellation Virgo.
