CZ Lacertae

CZ Lacertae Facts

  • CZ Lacertae is a pulsating variable star that can be located in the constellation of Lacerta. The description is based on the spectral class.
  • CZ Lacertae is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (F1) 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 -702.94 light years away from us. Distance

CZ Lacertae's Alternative Names

HIP110213 is the reference name for the star in the Hipparcos Star Catalogue.

CZ Lacertae has alternative name(s) :- CZ Lac, CZ Lac.

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

Location of CZ Lacertae

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 CZ Lacertae, the location is 22h 19m 30.73 and +51° 28` 14.8 .

Physical Properties of CZ Lacertae

CZ Lacertae Colour and Temperature

Based on the star's spectral type of F1 , CZ Lacertae'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.

CZ Lacertae Apparent and Absolute Magnitudes

CZ Lacertae has an apparent magnitude of 11.28 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 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 CZ Lacertae

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -4.64000 which gave the calculated distance to CZ Lacertae as -702.94 light years away from Earth or -215.52 parsecs. If you want that in miles, it is about -4,132,320,919,825,686.81, based on 1 Ly = 5,878,625,373,183.61 miles.

Variable Type of CZ Lacertae

The star is a pulsating RR Lyrae type with 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. CZ Lacertae brightness ranges from a magnitude of 11.576 to a magnitude of 10.756 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.4 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.
