Count me in too!!!

sorry if me they are bad expressed,(sorry, sorry for my poor english)
is probably that
to calculate the orbital parameters
it can be difficult,
and I must tanks bobdole for its add-on!!!!

but in celestia the luminosity is 0.00201 of sun... then: 0,37 times the sun... what's wrong??? post scriptum... but from wiipedia link: http://en.wikipedia.org/wiki/Gliese_581_c Temperature and habitability Scale comparison of the relative sizes of the Earth and Gliese 581 c, assuming Gliese 581 c ...

and and in fact as it wrote t00fri another similar little problem with add-on:

little differences with bobdolesrevenge1's add-on of gliese581 system and the stardat parameters???

this is easy for the stars of which I know the stc files the problem is that I wanted to change the texture of Gliese 581, but its parameters aren't present in the "nearstars.stc" file...(for example) and I don't open the star.dat file... (therefore I will have to gain the parameters from the astron...

I have noticed that star textures that I visualize on the program are the same ones... the color of stars is the same... white texture... also antares is white ... that is the problem? I have installed version 1.5.0 and also 1.4.1 version... and the error is the same one. the old version 1.3.2 inste...

the link above doesn't work for me too!!!

a new little planet founded in GL 581 star... the planet it's neptune like....Mass:0.056 MJ the M star it's near at home (20 ly), but has 1/3 sun mass information here... http://vo.obspm.fr/exoplanetes/encyclo/star.php?st=Gl+581 it's a very close to the star (orbital period 5.336 days ; Semi major a...

....why it's red???....

not problem for me...I have a 4 mega adsl...

goooood add-on....

maybe...

...or you can see the preprint in arxiv site.... http://it.arxiv.org/PS_cache/astro-ph/pdf/0407/0407620.pdf and more others.... http://it.arxiv.org/PS_cache/astro-ph/pdf/0507/0507004.pdf http://it.arxiv.org/PS_cache/astro-ph/pdf/0404/0404212.pdf http://it.arxiv.org/PS_cache/astro-ph/pdf/0402/0402542...

good...the most internal asteroid (earth - venus internal located)

here there are the asteroid's data... for ssc file...

for new add-on

very good news!!!

Do you have tried to simulate this ternary system with planets earthlike? for example with Gravity program... well, in this simulation, with a star (we consider for a moment two stars like one) in saturnian position,the planet jupiter comes endured expelled from the system, the Mars planet comes exp...

@Selden, you have reason...
