KP Muscae has alternative name(s) :- , KP Mus.

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

Location of KP Muscae

The location of the main sequence 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 KP Muscae, the location is 11h 31m 50.70 and -68° 03` 28.6 .

Physical Properties (Colour, Temperature) of KP Muscae

KP Muscae Colour and Temperature

KP Muscae has a spectral type of B3Ve. This means the star is a blue main sequence star. The star has a B-V Colour Index of 0.12 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 8,298 Kelvin.

KP Muscae Radius

Radius has been calculated as being 13.46 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 9,364,061.06.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.

KP Muscae Apparent and Absolute Magnitudes

KP Muscae has an apparent magnitude of 8.57 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 -2.37 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 KP Muscae

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.65 which gave the calculated distance to KP Muscae as 5017.90 light years away from Earth or 1538.46 parsecs. It would take a spaceship travelling at the speed of light, 5017.90 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

Variable Type of KP Muscae

The star is a eruptive Gamma Cassiopeiae variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted. KP Muscae brightness ranges from a magnitude of 8.681 to a magnitude of 8.545 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.1 days (variability).

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.
