What r the brightest stars visible in lite pollution? |
I'm in Bakersfield, CA, specifically in a suburb where 1 or 2 parks have their tennis court lights on in the early evening. & this question came 2 me while I biked down a poorly lit boulevard in my neighborhood. So which stars could b visible in a air- & light-polluted sky, besides Polaris? Polaris (Magnitude 1.97) is only the 48th brightest star, so if it is visible, the others in the top 50 should be visible too. Some are only visible, south of the equator, of course, and not all stars are circumpolar i.e. visible all night long in the northern hemisphere, all year round THE TWENTY BRIGHTEST STARS 1 鈭?.47 伪 CMa Sirius 8.6 light years away. 2 鈭?.72 伪 Car Canopus 310 light years away. 3 鈭?.04 var 伪 Boo Arcturus 37 light years away. 4 鈭?.01 伪1 Cen Alpha Centauri A 4.4 light years away. 5 0.03 伪 Lyr Vega 25 light years away. 6 0.12 尾 Ori Rigel 770 light years away. 7 0.34 伪 CMi Procyon 11 light years away. 8 0.50 伪 Eri Achernar 140 light years away. 9 0.58 var 伪 Ori Betelgeuse 430 light years away. 10 0.60 尾 Cen Hadar (Agena) 530 light years away. 11 0.71 伪1 Aur Capella A 42 light years away. 12 0.77 伪 Aql Altair 17 light years away. 13 0.85 var 伪 Tau Aldebaran 65 light years away. 14 0.96 伪2 Aur Capella B 42 light years away. 15 1.04 伪 Vir Spica 260 light years away. 16 1.09 伪 Sco Antares 600 light years away. 17 1.15 尾 Gem Pollux 34 light years away. 18 1.16 伪 PsA Fomalhaut 25 light years away. 19 1.25 伪 Cyg Deneb 3200 light years away. 20 1.30 尾 Cru Becrux 350 light years away. Sirius hasn't always been the brightest star in the sky, though. Algol is 92.8 light years from Earth; however, about 7.3 million years ago it passed within 9.8 light years of us and its apparent magnitude was approximately 鈭?.5, considerably brighter than Sirius is today. I think Orion's Belt are the brightest stars in the sky. I went to a planetarium a few days ago and that's what they said. Near Orion's foot, you'll find Sirius, the bluish-white Dog star. It's the brightest star in the night sky and you'll have no trouble spotting it...during Winter. Arcturus and Spica would also be a good star to look out for. To find them, go down the handle of the Big Dipper and find Arcturus southwest of the handle. To its southeast is Spica. Oh, and be on the look out for Jupiter and Mars. They don't twinkle and they often appear brighter than Sirius. Mars looks orangey, and the last time I saw Jupiter, it looked yellow to me. brucebirchall said it all. |
