Ice!
Nothing is speacil about it!
That is not known. Eris is too far away for us to know anything about its internal structure.
No. No spacecraft has gone past Eris, nor are there currently plans to send anything there.
Eris is a dwarf planet located in our solar system. Due to its extreme cold temperatures and lack of atmosphere, it is unlikely that any known organisms could survive on Eris. At present, there is no evidence of any life forms on this distant celestial body.
It is special not speacil. The answer is.... I suggest change it's forms and have battles. That's what I do with my Arceus in my Pokemon Black. I am not trading you. This is your answer. Thank you.
I heard from resources that we are not sure why Eris was called Eris.
after doing manaphy speacil mission (not available any more)you can transfer Pokemon from speacil missons to pearl/diamond.
Eris's moon Dysnomia, appears to be made of material similar to Eris and Eris appears almost grey.
No. Eris is much to far away to send astronauts there. We have not even sent any probes there. The only object astronauts have visited is the moon, which is much closer to Earth than any other object in space.

No. Eris is a dwarf planet.
No, there is absolutely no wind on Eris.
