Celestia Forums

Thanks. That's all I needed was a confirmation that there would be some blue.

I suppose this pertains to both the physics side and the Celestia side; I'm writing a series of stories and I want to be as realistic as possible for depicting the sky as seen on a planet that has an atmosphere comparable to Earth around a red giant. I had read from an online pdf (that I cannot find...

Thanks Selden. That's all I needed to know.

Have a question about temperature and thought I'd search for similar threads instead of making a new topic. I was wondering about the accuracy of the temperatures as I am building a fictional habitable world around a M9III giant with an AbsMag of 4.07. This is a world I'm using as a setting in a ser...

I had the same problem using Windows XP Pro SP2. The script will run and go through the warning page, ask for the output name, ask for the number of points, but didn't ask for any adaptive angle. When I input the minimum of 4 points, the script wouldn't do anything after that. Just tried it with 5 a...

I think any future Moon venture should be one in which scientists strive to build a permanent working base there, one which could be used as a stepping-stone for future missions to Mars and elsewhere.

That's the plan. We're not going back for goofs.

Using Gravity Simulator I placed a small moon 175 km radius and .005 Earth masses at a SMA of 500,000 km. This caused quite some havoc with the Moon's orbit and eventual both orbits became very elliptical with the new moon coming very close to the Earth. The same moon 350 km radius doesn't remain in...

Next time you are outside and the Moon is out, scale it with your out-stretched hand. I found that the Moon would fit inside my pinky fingernail! That's about a quarter of an inch.

The works of Stephen Hawking and Kip Thorne offer insight into black holes. Plus I'm sure there a number of technically accurate websites that do the same. Black holes were solutions to some equations derived from relativity theory. The theory predicted black holes. Then black hole candidates were f...

Just change the SMA and bring the Moon closer.

Ran across this doing a search for something else and it reminded me of a design that I came up with. http://i55.photobucket.com/albums/g133/psCargile/sfada/habitat_interior_03.jpg http://i55.photobucket.com/albums/g133/psCargile/sfada/habitat_interior_01.jpg http://i55.photobucket.com/albums/g133/p...

I did have a problem but I figured it out. Now my answers make sense. Thanks for all the help.

Meters! Alright, so if I input the semimajor axis in meters I should get results that make sense.

The model has some interior features that aren't needed. Currently the unfinished model is 29.8 MB. I can't upload this at my current and not expected to change anytime soon very slow dial-up internet connection. I download 1 MB in 15 to 20 minutes. It would take me about 8 hours to upload something...

I have no problem writing the ssc files, and I have Erin Dunn's System maker to make things easier. StarGen does a great job creating solar systems, however it doesn't do moons. I've noticed that Celestia (1.4.1) displays output and doesn't care if your inputs are impossible--I've put the Mir in a h...

Thanks bh. The tex files are too large for me to DL--no broadband available out here in the country, and not the fastest dial-up. LightTanis, I do 3d artwork myself, some of which can be seen here at my board . I consider myself more of a conceptual artist and a lot of my models remain to be finishe...

My main reason for using Celestia is creating fictional planetary systems. I want these planets and moons to have realistic orbits, periods, and rotations. I've made use of programs in the Motherlode utilities section--StarGen and the ssc file creator. Plus I'm using Gravity Simulator to check out t...

In v 1.4.1 you can take the align.log data: Orientation: [0.0133964,0.999795,0.0151858], 133.005 read as Orientation: [x-axis, y-axis, z-axis], angle and convert it to the ssc data: Orientation [ 133.005 0.0133964 0.999795 0.0151858 ] read as Orientation [angle x y z] or Orientation [ 133.005 0 1 0 ...

Should people have freedom of choice?

I'm sure there is lots of things that happen the US that aren't considered newsworthy to European media.
