# Question #f8a1b

If you moved Deneb to the Alpha Centauri distance, it would appear ${\left(\frac{2600}{4.37}\right)}^{2}$ = 354,000 times brighter than it is now. Rigel would be 39,000 times brighter. Both would certainly be brighter then Venus at its brightest. In Deneb's case, possibly ten times as bright as a full moon.
