FINALLY the cloud cleared today, and feeling like Trinity seeing the clear sky for the first time, in the Matrix sequel, I went up to the castle and got some pics...
That last one shows the ISS moving through the sky too... -------------------- |

Once again working in Arica Chile.
I can tell you that it's even more spectacular sitting on a beach, wearing shorts and having a beer . I'll try to take a shot tonight. -------------------- |

Admiring dazzling Venus on this chilly Michigan evening I wondered this: if it had a moon of similar size and orbital characteristics to our own, would it be a naked eye object?

Admiring dazzling Venus on this chilly Michigan evening I wondered this: if it had a moon of similar size and orbital characteristics to our own, would it be a naked eye object? Yes, for much of its orbit - and not too lost in glare. A quick calculation here (there's nothing better to do since I'm clouded out from any observing today) and I'm getting a range of magnitudes for the Venusian Moon up to "our Mars" in terms of brightness. The separation is impressive: at favourable points in its orbit, there'd be .3 to .5 degrees between Venus and its Moon. (Contemplative Alternative History Guess) For pre-telescopic observers I suspect a heliocentric theory would develop quite quickly. What would be particularly cute is that there would be stages in the orbit where Moonshine or Venusshine would be telescopically obvious. Andy |
