Post #1by AlextheFirst » 09.12.2002, 20:30

anybody data for stc file?
There is Hektor add-on - is this `think` realy exist is solar system?
I`m searching for stars catalog with could help me to create small stc files with interresting stars. It (thin cat.) should have data for ap. magnitude and radius of stars. Could sbd help me to find it?

Hi,

If i'm not wrong the radius of Sirius B is slightly smaller than Earth's, 5850 km as i found on the net, at least this is the setting i'm using. I've got no idea if there's a Sirius C :?:

Yes, the 624 Hektor contact binary asteroid is real, take a look at this pic:

I`ve changed title of this post. Redfish, You`re, of course, right. Realy sorry. I should pay more attention what i`m writting. Sorry. :oops:



Is it possible that Sirius B is so small? Isn`t it normal star?


Thank for all replys.

Hey Rass,
Maybe he doesn't know the diference between a normal star and a white dwarf. I would hope he does.

AlextheFirst,
The easist way to explain a white dwarf is to call it the burned out cinder of a star that was the size and mass of our star. The only reason they apear white is because there still white hot and haven't cooled down. Once they cool they no longer will give any light.
I am officially a retired member.
I might answer a PM or a post if its relevant to something.

Ah, never say never!!
Past texture releases, Hmm let me think about it

Thanks for your understanding.
