Gliese 758 is a star in the northern constellation of Lyra. At about magnitude 6 it is a challenge to view with the naked eye even in good seeing conditions, but can be easily seen through a small telescope or binoculars.

Nov 24, 2010 · GJ 758 B is a cold (~600K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging. Here we present photometry of the companion in seven...

Dec 3, 2009 · The object, known as GJ 758 B, could be either a large planet or a “failed star,” also known as a brown dwarf. The faint companion to the sun-like star GJ 758 is estimated to be 10 to 40 times as massive as Jupiter and is a “near neighbor” in our Milky Way galaxy, hovering a mere 300 trillion miles from Earth.

Dec 4, 2009 · The new planet candidate, GJ 758 B, was discovered around a G star GJ 758A (note 1) at a distance of 50 light-years from the Sun by an international team composed of members from Germany,...

In this paper we present high-contrast imaging observations of GJ 758, using HaleP1640, where we obtain the rst low-/ fi resolution near-IR spectrum of the B companion, at four epochs, and model the companions temperature, surface ’ gravity, and spectral type.

Jan 24, 2011 · GJ 758 B is a cold (~600 K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging. Here, we present photometry of the companion in seven photometric bands from Subaru/HiCIAO, Gemini/NIRI, and Keck/NIRC2, providing a rich sampling of the spectral energy distribution in the 1–5 μm ...

Mar 20, 2017 · The nearby Sun-like star GJ 758 hosts a cold substellar companion, GJ 758 B, at a projected separation of ≲30 au, previously detected in high-contrast multi-band photometric observations.

Mar 3, 2017 · GJ 758 B was detected in four epochs during 2013 and 2014. Basic astrometric measurements confirm its apparent northwest trajectory relative to the primary star, with no clear signs of orbital curvature.

GJ 758 B is a cold ( ∼600 K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging.

GJ 758 B is a brown dwarf companion to a nearby (15.76%) solar-type, metal-rich (M / H = + 0.2 dex) main-sequence star (G9V) that was discovered with Subaru/HiCIAO in 2009. From previous studies, it has drawn attention as being the coldest (~600 K) companion ever directly imaged around a neighboring star.
