Well finally get into some adult college (Night School) for Astronomy class (about the Solar System) ><...yea the first day was cool (Watching TV), but the 2nd day... ok never mind here's the question :
>< big problem I haven't learn about using the intensity ratio formula before ><...when Mars made its closet approach to Earth, it shone very brightly with a magnitude of -2.9. Use the intensity ratio formula for magnitudes to compare this brightness to the star Fomalhaut (aphla Piscis Austrini), which ranks among the brightest stars in the sky with a magnitude of +1.1 and which appears to the South of Mars inAugust of 2003. Which appeared brighter, Mars or FomalHaut? How Many times brighter?
