Location of Luhman 16

The location of the dwarf star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For Luhman 16, the location is 10h 49m 18.723 and 53° 19` 9.86 .

Luhman 16 Apparent and Absolute Magnitudes

Luhman 16 has an apparent magnitude of 8.87 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Distance to Luhman 16

Luhman 16 is an estimated 6.52 light years from our Solar System (Earth and Sun). It would take a spaceship 6.52 years travelling at the speed of light to get there. We don't have a space ship that can travel that distance or at that speed yet.

I think the Visual apparent magnitude is more like 23. 8.87 may be the infrared apparent magnitude?
