Hey everyone!

Wanna know your age in Jupiter years?
Just divide it by 12!
That's because Jupiter takes 12 years to go around the sun (duuh... most of you probably know that...).

My Earth Age is about 20yr
Which in Jupiter years would be aproximately...
1 year and 7 months...

How pathetic we are...

PS: I'm just bored. I'm doing an Astronomy lab and I have to capture some millions of photons to analize a star's wavelenghts...

Well. to be accurate, since a "month" is based on the orbital period of our Moon, a Jupiter month should be based on a Jovian Moon. Io would be the Largest as seen from Jupiter, and has a period of 4.31 Jovian days. Thus there would be 2448 "months" in a Jovian year, and you would be about 1yr and 1664 months old.

hahahahaha
Wait a sec... period of about 4 Jovian day? mere 40+ hours?

Earthling: Look! 5 full moons in a week?
Jupiterean: No, only two.....

(AHHHH, I always mess up with jokes....)

Common guys! Post your Jupiter years!

I'm sure nobody is older than 8 years old...

Ahhh...! I'm still collecting photons out of a simulated telescope for the astronomy assignment! Arrgh...! It takes such a looooooooong time. I still have a signal-to-noise relation of 12.9, and I need something more like 100...(after an hour....)! This takes forever...

Well, if we are going to talk weeks...

The Earth week was originated from the the fact that there are seven Naked-eye visible heavenly Bodies in the sky, (Moon, Sun , Venus, Mercury, Mars, Jupiter, Saturn). Which is why we have Sunday, Mo(o)nday, and Satur(n)day. The other planets were renamed for their saxon equivalents: Jupiter -Thor; Thor's day ;Thursday
Mercury -Wodin; Wodin's day; Wednesday
Mars- Tyr (Tiw); tiw's day ; Tuesday
Venus - Freya; Freya's day ; Friday

So, for Jupiter, following the same pattern, we would still have Sunday, Saturday, Tuesday and Friday. No Thursday, no Monday and no Wednesday (Mercury would be lost in the sun's glare.) . And we will have a new day for Earth (Geoday?)

But also Jupiter has several moons. Now the big four ( Io, Europa, Ganymede & Callisto) will definitely be bright enough, so we'll have Ioday, Euroday, Ganyday and Callisday.)

The four closer moons are small, but close enough to see also, so we will also have: Metisday, Adrasday, Almathday and Thebesday

The moons further out are to small and dim to be naked eye visible.

This would give us a thirteen day week and three months to a week.

3 months to a week? Oh yeah, I just remembered my own post lol..... one Jupiter month is about 3 Jupiter days with your definition....., uh I mean, 4....... duh....

By the way, truth, I'm just about as old as you.... so I won't recalculate.

Oh, m, by the way, Janus, care to apply your calculations to other planets except mercury (based on your idea, Mercury would have at most 3 days, maybe only two, and it won't have any moon), and maybe venus?

Ok...

Btw, Janus58, how old are you in Jupiter years...?

Wow...! You are almost 3 years older than me...

U would actually be a little younger than what u calculate coz time is flowing a little slower in the stronger gravitational field according to relativity

Good observation

But I think the difference would be just in the order of days... or maybe even hours...

More like fractions of a second.

I'm just over 1/8th of a Pluto year old, or about 1830 Pluto days. Pluto has no months, since it's tidally locked with Charon.

You could possibly argue for a 6 day week (Sun, Charon, Neptune, Uranus, Jupiter, Saturn, although I don't know how visible they would be), making me just over 300 Pluto weeks old.

Well, once you start breaking it down to months, days, and weeks, you'll first need to consider the difference between sidereal months/days and solar months/days.

Exactly, theres a few changes to what we measure as age on the earth. Just trying to be thorough thats all!!!

I would be exactly 1.2 years old, rounded of course.

:bugeye:

So which is it? Exact, or Rounded? The terms are contradictory!

(Yeah, I'm a pedant )

I'm 1 year and 1020 months, Jovian, old.

Never mind all that, does anyonw know when Cassini/Hyugens is due to arrive at Titan?

(I'll be over in the Religion tent, on the 'Islam Is Better Than Christianity' thread, annoying Muslims-- it's great fun!).
