V4046 Sagittarii – K-type main-sequence star

V4046 Sagittarii – K-type main-sequence star

V4046 Sagittarii is a constellation. It is a young binary star system made up of two K-type main-sequence stars. The two stars are approximately 271 light-years (83 parsecs) apart from Earth. It is not found within the Solar System; the Solar System contains only one star, the Sun. The two stars orbit each other in a circular orbit every 2.42 days. It is not part of the Sagittarius constellation outline, but it is within its boundaries. The color of V4046 Sagittarii is orange to red based on the star’s spectral type (K5+K7 D). It is 236.16 light years away from Earth.

When you look at V4046 Sagittarii, you are actually looking back in time, seeing how it looked years ago. Changing the distance from light years to years will roughly tell you how long ago we are looking at the star. There are no Exoplanets recorded on the site for the star, which is most likely the case.

V4046 Sagittarii is surrounded by a massive protoplanetary disk. The disk has a radius of about 370 astronomical units (au) and contains approximately 40 Earth masses of dust. There are two bright inner rings 14 and 25 au from the center, respectively.


TW Hydrae, HD 141569, and 49 Ceti are the other three pre-main-sequence star systems with protoplanetary disks within 100 parsecs of V4046 Sagittarii. The two stars are still absorbing matter from the disk, and gas giant planets may be forming as well.

The star’s parallax is given as 13.81110, resulting in a calculated distance to V4046 Sagittarii of 236.16 light years or 72.41 parsecs from Earth. It is approximately 1,388,296,168,131,041 miles away from Earth. The star is approximately 14,935,530.55 Astronomical Units, give or take a few. The distance between Earth and the Sun is measured in Astronomical Units. The number of A.U. denotes how far away the star is from the Earth in comparison to the Sun.

The red dwarf GSC 07396-00759 is separated about 2.82″ from V4046 Sagittarii. Since it has a similar motion throughout space with V4046 Sagittarii, GSC 07396-00759 is assumed to be gravitationally bound (although weakly) to V4046 Sagittarii. The two systems are separated by at least 12,350 astronomical units (0.1953 ly) away, and the orbital period would be on the order of 100,000 years. GSC 07396-00759 itself has an edge-on debris disk with a radius of 70 au, and may be a binary as well, making V4046 Sagittarii a potentially quadruple system.
