stellar radius उदाहरण वाक्य
उदाहरण वाक्य
- This conclusion, if further corroborated, would suggest an average angular diameter for Betelgeuse closer to Perrin's estimate at 43.33 arcseconds, hence a stellar radius of about 3.4 AU ( 730 R & ) assuming the shorter Hipparcos distance of 498 ?73 ly in lieu of Harper's estimate at 643 ?146 ly.
