HIP 94736's Alternative Names

HIP94736 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD180713.

BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+24 3699.

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

Location of HIP 94736

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 HIP 94736, the location is 19h 16m 39.12 and +24° 16` 50.0 .

Physical Properties of HIP 94736

HIP 94736 Colour and Temperature

Based on the star's spectral type of B9 , HIP 94736's colour and type is blue star. The star has a B-V Colour Index of 0.12 which means the star's temperature is about 8,178 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

HIP 94736 Radius

HIP 94736 estimated radius has been calculated as being 256.86 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 178,722,457.90.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 rather than peer reviewed papers. It has been known to produce widely incorrect figures.

HIP 94736 Apparent and Absolute Magnitudes

HIP 94736 has an apparent magnitude of 8.28 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 -8.71 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 94736

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.04000 which gave the calculated distance to HIP 94736 as 81540.84 light years away from Earth or 25000 parsecs. If you want that in miles, it is about 479,348,050,974,705,033.63, based on 1 Ly = 5,878,625,373,183.61 miles.

Travel Time to HIP 94736

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.

Multi-Star System

The star has been identified as being a multi-star system, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point. The stars may be of equal mass, unequal mass where one star is stronger than the other or be in groups orbiting a central point which doesn't necessarily have to be a star. More information can be found on my dedicated multiple star systems page. The source of the info is Simbad. The file is dated 2000 so any differences between this and any other source will be down to the actual source from where the information came from.
