HIP 66441

Primary Facts on HIP 66441

  • HIP 66441's star type is star that can be located in the constellation of Canes Venatici. The description is based on the spectral class.
  • HIP 66441 is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (G0) of the star, the star's colour is white to yellow .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • The star is calculated at being about 157.57 light years away from us.

HIP 66441's Alternative Names

HIP66441 is the reference name for the star in the Hipparcos Star Catalogue. The Gliese ID of the star is GL 518.2B. The star was part of the original catalogue devised by German Astronomer Wilheim Gliese of stars located within 20 parsecs of Earth. Star Names

Location of HIP 66441

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 star is compared to the celestial equator and is expressed in degrees. For HIP 66441, the location is 13h 37m 13.92 and +30° 05` 13.8 .

Physical Properties (Colour, Temperature) of HIP 66441

HIP 66441 has a spectral type of G0. This means the star is a white to yellow star. The star has a B-V Colour Index of 0.85 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,308 Kelvin.

HIP 66441 Radius has been calculated as being 0.40 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 276,347.23.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 66441 Apparent and Absolute Magnitudes

HIP 66441 has an apparent magnitude of 10.64 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 7.22 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 66441

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 20.70 which gave the calculated distance to HIP 66441 as 157.57 light years away from Earth or 48.31 parsecs. It would take a spaceship travelling at the speed of light, 157.57 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.
