SAO 206462 is a young binary star, surrounded by a circumstellar disc of gas and clearly defined spiral arms.
[4] The presence of these spiral arms seems to be related to the existence of planets inside the disk of gas surrounding the star.
[5] The discovery of this object was presented in October 2011 by Carol Grady, astronomer of Eureka Scientific, headquartered in the Goddard Space Flight Center at NASA.
[6] The pair of spiral arms around SAO 206462 have a rotation rate of −0.85 degrees per year, which are thought to be caused by a dynamically driving protoplanet within the disk, at a distance of 66±3 astronomical units and an orbital period of 424±25 years.
[7] Another planet candidate around SAO 206462 has been detected using observations of the JWST's NIRCam imaging instrument, with low signal-to-noise ratio, a mass of 0.8±0.3 MJ and a separation of 300 astronomical units.
