HIP 105736 Facts

HIP 105736's Alternative Names

HIP105736 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD203598.

More details on objects' alternative names can be found at Star Names .

Location of HIP 105736

The location of the giant 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 HIP 105736, the location is 21h 24m 58.16 and -49° 35` 36.9 .

Physical Properties (Colour, Temperature) of HIP 105736

HIP 105736 Colour and Temperature

HIP 105736 has a spectral type of K0/K1III. This means the star is a orange to red giant star. The star has a B-V Colour Index of 1.23 which means the star's temperature is about 4,439 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu at being .

HIP 105736 Radius

Radius has been calculated as being 978.19 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 680,621,251.53.km. If you need the diameter of the star, you just need to multiple the radius by 2. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

HIP 105736 Apparent and Absolute Magnitudes

HIP 105736 has an apparent magnitude of 9.53 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 -8.96 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 HIP 105736

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.02 which gave the calculated distance to HIP 105736 as 163081.67 light years away from Earth or 50000 parsecs. If you want that in miles, it is 109,365,279,787,090.

Travel Time to HIP 105736

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.

Source of Information

The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
