CC Lyrae

CC Lyrae Facts

  • CC Lyrae is a pulsating variable star that can be located in the constellation of Lyra. The description is based on the spectral class.
  • CC Lyrae is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (FOp) of the star, the star's colour is yellow to white .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • The star is calculated at being about 2508.95 light years away from us. Distance

CC Lyrae's Alternative Names

HIP91015 is the reference name for the star in the Hipparcos Star Catalogue.

CC Lyrae has alternative name(s) :- CC Lyr, CC Lyr.

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

Location of CC Lyrae

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 CC Lyrae, the location is 18h 33m 57.41 and +31° 38` 24.2 .

Physical Properties of CC Lyrae

CC Lyrae Temperature and Colour

Based on the star's spectral type of FOp , CC Lyrae's colour and type is yellow to white variable star. Based on the star's spectral, the stars temperature is between 6,000.00 and 7,500.00 degrees kelvin.

CC Lyrae Radius

CC Lyrae Iron Abundance

CC Lyrae Iron Abundance is -2.12 with an error value of 9.99 Fe/H with the Sun has a value of 1 to put it into context. The value comes from the Hipparcos Extended Catalog.

CC Lyrae Apparent and Absolute Magnitudes

CC Lyrae has an apparent magnitude of 12.01 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 2.58 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 CC Lyrae

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 1.30000 which gave the calculated distance to CC Lyrae as 2508.95 light years away from Earth or 769.23 parsecs. If you want that in miles, it is about 14,749,177,130,049,018.31, based on 1 Ly = 5,878,625,373,183.61 miles.

Travel Time to CC Lyrae

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 CC Lyrae

The star is a pulsating W Virginis Stars, A 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. CC Lyrae brightness ranges from a magnitude of 12.551 to a magnitude of 11.767 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 23.9 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.
