BF Sculptoris Facts

  • BF Sculptoris is a pulsating variable star that can be located in the constellation of Sculptor. The description is based on the spectral class.
  • BF Sculptoris is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (K5) of the star, the star's colour is orange to red .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • The star is calculated at being about 2416.02 light years away from us. Distance

BF Sculptoris's Alternative Names

HIP6536 is the reference name for the star in the Hipparcos Star Catalogue.

BF Sculptoris has alternative name(s) :- , BF Scl.

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

Location of BF Sculptoris

The location of the variable 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 BF Sculptoris, the location is 01h 24m 01.09 and -37° 35` 59.0 .

Physical Properties of BF Sculptoris

BF Sculptoris Temperature and Colour

Based on the star's spectral type of K5 , BF Sculptoris's colour and type is orange to red variable star. The star has a B-V Colour Index of 1.57 which means the star's temperature is about 3,854 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

BF Sculptoris Radius

BF Sculptoris estimated radius has been calculated as being 24.84 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 17,280,967.05.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.

BF Sculptoris Apparent and Absolute Magnitudes

BF Sculptoris has an apparent magnitude of 8.98 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 -0.37 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 BF Sculptoris

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 1.35000 which gave the calculated distance to BF Sculptoris as 2416.02 light years away from Earth or 740.74 parsecs. If you want that in miles, it is about 14,202,876,474,119,065.43, based on 1 Ly = 5,878,625,373,183.61 miles.

Travel Time to BF Sculptoris

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.

Variable Type of BF Sculptoris

The star is a pulsating Semi-Regular Star w 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. BF Sculptoris brightness ranges from a magnitude of 9.227 to a magnitude of 9.011 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.2 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.
