GQ Lupi

GQ Lupi is a T Tauri variable star approximately 495 light-years away[3] in the constellation of Lupus.

[8] In 2020, another low-mass companion of GQ Lupi was discovered at a separation distance of about 16 arcseconds, or 2400 AU.

Designated 2MASS J15491331-3539118 under the 2MASS catalogue, it is likely a young stellar object that is gravitationally bound to its primary star.

[6] In 2005, Ralph Neuhäuser and his colleagues reported a substellar object, GQ Lupi b, orbiting the star.

[9] As of 2006, the International Astronomical Union Working Group on Extrasolar Planets described GQ Lupi b as a "possible planetary-mass companion to a young star".

VLT NACO image, taken in the Ks-band, of GQ Lupi. The feeble point of light to the right of the star is the newly found cold companion. It is 250 times fainter than the star itself and it located 0.73 arc second west. At the distance of GQ Lupi, this corresponds to a distance of roughly 100 AU . North is up and East is to the left.
