R Lyncis is a pulsating star that can be located in the constellation of Lynx. The star can not be seen by the naked eye, you need a telescope to see it.
HIP33824 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD51610.
R Lyncis has alternative name(s), R Lyn.
The location of the star in the galaxy 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 R Lyncis, the location is 07h 01m 18.01 and +55d 19` 49.8 .
R Lyncis has a spectral type of S3,9e. This means the star is a star. The star has a B-V Colour Index of 2.08 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 1,306 Kelvin. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.
R Lyncis has an apparent magnitude of 9.93 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.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -3.39 which gave the calculated distance to R Lyncis as -962.13 light years away from Earth or -294.99 parsecs. It would take a spaceship travelling at the speed of light, -962.13 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
The star is a pulsating Omicron Ceti 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. R Lyncis brightness ranges from a magnitude of 11.916 to a magnitude of 7.626 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 374.0 days (variability).
