Christmas On Other Worlds

Looking pensively at the twinkling lights on our Christmas Tree I pondered what time of year it is on other Worlds in our Solar System. When would Christmas be? And as I'm a December baby how old would I be on our fellow planets?

The answer to this last question, my nine ages, is as follows [in the named planet's years and in order of the planets' positions to the Sun]:

1. Mercury 203
2. Venus 79
3. Earth Top Secret
4. Mars 26
5. Jupiter 4
6. Saturn 1 and a half
7. Uranus 6 months
8. Neptune 3 months
9. Pluto 2 months

I'm just a Plutonian baby! The next time it will be Christmas across the Solar System will be:

1. Mercury 2011
2. Venus 2011
3. Earth 2011
4. Mars 2012
5. Jupiter 2021
6. Saturn 2020
7. Uranus 2045
8. Neptune 2126
9. Pluto 2210
