Here is a drawing that could be of some help. first, some portuguese: Precess??o do P??lo Sul = Precession of the South Pole a.C = BC d.C = AD Cruzeiro: Southern Cross GNM= LMC (Large Magellanic Cloud) PNM= SMC (small Magellanic Cloud) =>note how close it is from the precession cycle!! P??lo da Ecl?...

Sadly, they were 21 engineers in fact.

Despite?? I would say that this explains the lack of metallic resources!!

Very good job indeed, Dr. Fridger. Congratulations!
And thanks for your efforts.
I can hardly wait for the enhancements that will come up from today's flyby.

Bye!

Tony,

even if the object is in ressonance with the Moon?

We know the apparent magnitude of a full moon from Earth is about -13. But what's the apparent magnitude of a full Earth as seen from the moon? I know it'd be brighter, but I've never seen a number for this... Just a guess: The area of Earth's disk as seen from the Moon is 13.5 times the area of th...

Also, the new version will have support for greenhouse effects on planets in ssc files? It's because the temperatures on Venus and on Earth are wrong. For you have an idea, Venus temperature is 231K and Earth is 259K. It's wrong, right? That would be a good idea. One could include a line in the ssc...

Sometimes, in old books , I saw the "F" stars represented with green colour. So, in my childhood I thought that green stars did exist. It was much later that I discovered that was not true. There is a very good discussion on this matter here: http://www.madsci.org/posts/archives/may97/859923240.As.r...

I'd like to thank you for the link. It was very interesting.
Quite impressive screenshot.

Just an observation:
If we use a mass greater than 85 solar masses for Pistol Star, then your "Pistol-Pluto" would have a period smaller than 27 years, considering a semi-major axis of 39.5 A.U.

Hi, Thanks for your replies! :wink: Chris, I understand that they never worked right but in 1.3.1 there was, at least, some kind of shadow while in 1.3.2 there isn't any... :cry: But it's ok! It's just a small detail in a great software. I'll wait for the upgrades. bye! Fafers Eclipses shadows on ir...

Greetings from Brazil, First of all, I apologize for my poor english... Celestia is great! Congratulations for its creator and all the colaborators. Now the question: I've just upgraded from Celestia 1.3.1 to 1.3.2. I know that irregular bodies do not cast shadows on planets. But in Celestia 1.3.1, ...
