White Dwarf Jupiter

Post #1by PlutonianEmpire » 26.04.2006, 12:57

Three questions:

1) What is the chemical make up of Jupiter, in percentages?

2) How big would jupiter be if we were some how able to compress it into a star (It does not matter to me wether or not it fuses, just as long as it can be lit up or ignited for whatever amount of time)?

3) How do I make the default planet jupiter orbit another star using the "modify" SSC command? (I ask because jupiter's moons flicker with the new star in it's place)

http://en.wikipedia.org/wiki/Jupiter

Specifically, the table on the right, at the bottom. Wikipedia is your friend, not to mention google.

I have no idea. I'd guess pretty tiny; less than a mile in diameter.

This is a result of doing a google search. See

http://en.wikipedia.org/wiki/Jupiter_(planet)

As impressive as Jupiter's mass is, extrasolar planets have been discovered with much greater masses. There is no clear-cut definition of what distinguishes a large planet such as Jupiter from a brown dwarf star, although the latter possesses rather specific spectral lines. Currently, if a supermassive object is above 12 Jupiter masses, large enough to burn deuterium, it is considered a brown dwarf star; below that mass, it is a planet. Jupiter is thought to have about as large a diameter as a planet of its composition can; adding extra mass would result in further gravitational compression, in theory leading to stellar ignition. This has led some astronomers to term it a "failed star", although Jupiter would need to be about seventy times as large to become a star.

The flickering may be a result of Jupiter still existing. Comment it out of the solarsys.ssc file. I assume you created the White Dwarf Jupiter in an stc file?

Yes.

From what I can tell, the flickering ceases when I put planet jupiter around jupiter star, but that would mean altering every single solar system moons file to get all of jupiter's moons into the new system. I really would rather not have to do that, but if I do have to, thank goodness for Microsoft Office Word for it's "find and replace words" feature. ;)

EDIT: Another question, would the star be bright enough to cast shadows on Earth, or from space, see Earth's nightside illuminated somewhat?

I don't think it's possible. Perhaps you could try using Runar's th_placeholder.3ds as a mesh for Jupiter.

What's the mesh for, and where can I find it?
