The location of the cool methane 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 WISE 0458+6434 A, the location is 04h 58m 54.00 and 64° 34` 53.00 .
Based on the star's spectral type of T 8.5 , WISE 0458+6434 A's colour and type is brown cool methane dwarf Star.
WISE 0458+6434 A Radius has been calculated as being 0.10 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 68,188.40.km. If you need the diameter of the star, you just need to multiple the radius by 2.
The star is believed to be about 1.00 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.
The Parallax of the star is given as 95.23810 which gives a calculated distance to WISE 0458+6434 A of 34.25 light years from the Earth or 10.50 parsecs. It is about 201,342,919,031,539 miles from Earth.
The star is roughly 2,165,765.37 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.
The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).
The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
