Suppose Pluto had the same orbit around the Sun as Mars. When closest to
Earth, how bright would Pluto be? A. Pluto would still be so faint that you'd need a telescope to see it. B. Pluto would be bright enough to see through binoculars, but not with the naked eye. C. Pluto would be one of the brightest objects in the sky, outshining every star except the Sun. Find out the correct answer at http://KenCroswell.com/PlutoQuestion.html .

Pluto would be bright enough to see through binoculars, but not with the naked eye. C. Pluto would be one of the brightest objects in the sky, outshining every star except the Sun. Simple: C. Pluto's absolute magnitude is only 0.7 mag fainter than Mars' absolute magnitude, so Pluto would be only 0.7 mag fainter than Mars when in the same location in the Solar System. During Mars' perihelic opposition three years ago, it reached an apparent magnitude of -2.9, so Pluto would be -2.2, brighter than Sirius (about twice as bright). So? By the way, the Sun isn't a star: it's a dwarf star. It's the new IAU nomenclature; a dwarf something is no longer a something. I wonder when the AKC will declare that toy poodles are no longer poodles? |

I wonder when the AKC will declare that toy poodles are no longer poodles? The way I understand it is that a dwarf star is still a star, and a dwarf galaxy is still a galaxy, but a dwarf planet is not a planet. (We do know that toy poodles are too small to be raal dogs - real dogs go WOOF, not yap-yap-yap. G) Clear skies, Alan |

If you wish to have a joke don't whine when it comes back to you. The key word here is "if". No joke was involved on my part, Sorcerer. I said nothing about puddles, dorsets, or Poole. Non sequitur. Classic unsubstantiated and erroneous claim. Androcles. Non sequitur. |
