19 Lyncis's Alternative Names

The Id of the star in the Yale Bright Star Catalogue is HR2783. HIP35783 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD57102.

Flamsteed designations are named after the creator, Sir John Flamsteed. Sir John named the stars in the constellation with a number and its latin name, this star's Flamsteed designation is 19 Lyncis A. The Flamsteed name can be shortened to 19 Lyn A.

BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+55 1192A.

Location of 19 Lyncis

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 19 Lyncis, the location is 07h 22m 50.85 and +55° 17` 03.8 .

Physical Properties of 19 Lyncis

19 Lyncis Temperature and Colour

Based on the star's spectral type of B9V , 19 Lyncis's colour and type is blue main sequence star. The star has a B-V Colour Index of -0.05 which means the star's temperature is about 10,395 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

19 Lyncis Radius

19 Lyncis estimated radius has been calculated as being 1.37 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 949,998.54.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.

19 Lyncis Apparent and Absolute Magnitudes

19 Lyncis has an apparent magnitude of 6.86 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 1.62 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 19 Lyncis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 8.94000 which gave the calculated distance to 19 Lyncis as 364.84 light years away from Earth or 111.86 parsecs. If you want that in miles, it is about 2,144,757,681,152,308.27, based on 1 Ly = 5,878,625,373,183.61 miles.

Travel Time to 19 Lyncis

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.

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.

Multi-Star System

The star has been identified as being a multi-star system, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point. The stars may be of equal mass, unequal mass where one star is stronger than the other or be in groups orbiting a central point which doesn't necessarily have to be a star. More information can be found on my dedicated multiple star systems page. The source of the info is Simbad. The file is dated 2000 so any differences between this and any other source will be down to the actual source from where the information came from.
