HV 11423

HV 11423 Facts

Location of HV 11423

The location of the 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 HV 11423, the location is 1h 00m 55.20 and -71° 37` 52.9 .

Physical Properties (Colour, Temperature, Radius) of HV 11423

HV 11423 Colour and Temperature

HV 11423 has a spectral type of M0 1ab. This means the star is a red star. The star has a B-V Colour Index of 1.88 which means the star's temperature is about 2,591 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu at being .

HV 11423 Radius

HV 11423 has been calculated as 1,220.00 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 848,876,000.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

HV 11423 Apparent and Absolute Magnitudes

HV 11423 has an apparent magnitude of 11.84 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of -3.96 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 HV 11423

The Parallax of the star is given as 0.07 which gives a calculated distance to HV 11423 of 47133.43 light years from the Earth or 14450.87 parsecs. It is about 31,608,461,939,807 miles from Earth.

The star is roughly 2,980,685,130.95 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.

Travel Time to HV 11423

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.
