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?



Cheers, Alex.

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:

QWhy is the subject title rubbish?
can't you change it?

rubbish? it says dont read this

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.



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


Thank for all replys.

Its a White Dwarf...

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 more than less know this difrence, i just was sure that Sirius B is realy, realy normal star .
And Sirius C? I think i saw a few times ago article about discovery of C,
and they even draw orbits! -- BUT i`m not sure now...

see this page and it's links:

Note it's a Binary system: A & B but no C.
