All Rr Lyrae Stars Have About The Same

Rr lyrae distance from earth. Using the original hipparcos data that was released in 1997, the parallax to the star was given as 4. 38000 which means rr lyrae distance from earth is 744. 67 light years away from earth or 228. 31 parsecs. If you want that in miles, it is about 4,377,635,956,648,638. 86, based on 1 ly = 5,878,625,373,183. 61 miles. The present determination of the absolute magnitude. m v (rr) of rr lyrae stars is twofold, relying upon hipparcos proper motions and trigonometric parallaxes separately.
