how far is the star sirius from earth
Sirius Sirius appears bright because of its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite,[2][25][26] the Sirius system is one of Earth's near neighbours. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to increase and it will become fainter, but it will continue to be the brightest star in the Earth's night sky for the next 210,000 years.[27]
Religio The Latin term
Day's journey In the Bible, it is not as precisely defined as other Biblical measurements of distance; the distance has been estimated from 32 to 40 kilometers (20â€“25 miles).
