Location of HIP 66437

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 66437, the location is 13h 37m 11.62 and -47° 00` 56.1 .

Physical Properties (Colour, Temperature) of HIP 66437

HIP 66437 Colour and Temperature

HIP 66437 has a spectral type of B5III. This means the star is a blue giant star. The star has a B-V Colour Index of -0.05 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 10,395 Kelvin.

HIP 66437 Radius

Radius has been calculated as being 202.93 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 141,198,328.92.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 66437 Apparent and Absolute Magnitudes

HIP 66437 has an apparent magnitude of 7.75 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 -9.24 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 66437

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.04 which gave the calculated distance to HIP 66437 as 81540.84 light years away from Earth or 25000 parsecs. It would take a spaceship travelling at the speed of light, 81540.84 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

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.
