i, personally have read an article about a new 'planet' or 'asteroid' or watever u may call it and i jus want to hear the people's opinion about it.... on BBC they said it MAY be possible that planet sedna or rock sedna has the requirements of a second earth, water, temperature, and gravity but wat i think from that distance it is from pluto man will need lots and lots of technology to piece together to actually travel there let alone send a driod for survillence do u guys think its another planet or jus a rock :confused:

I've been looking on NASA's site and following that.

It's interesting.

the distance shown at the BBC website shows that pluto is actually (on the small picture) about (estimated) 4 cm away from sedna.... i dont think its possible for any country to possess the technology to reach that far now.....

I think you're right.

I wonder if they could launch something similar to hubble to at least get close enough to really see it?

Sure you're not mixing something up? According to NASA this Sedna is smaller than the moon (so it probably doesn't have an atmosphere), rather cold (-240 degrees celsius) and three times as far away as Pluto.

I read on BBC though that someone recently discovered a planet about 20 light-years from here that could support life.

It's interesting that there's a planet relatively "close" which may be livable for humankind: perhaps we have some hope after all, eventually technology will be developed enough to actually build such a vessel that can reach this new planet in acceptable time.

Sedna is, by no classification system I know of, a planet. Nor has it ever been considered remotely likely that it could support any Earthly life, given that it is too far from the sun, too small to support a viable atmosphere, and doesn't appear to have any water.

If, however, you're referring to that extra-solar planet that has been causing such a stir in the news recently, the name of which escapes me, I can't help you. There have been so many conflicting reports that I wouldn't know where to begin. From what I have read, though, it seems that the fact that this planet has simply had its size compared to that of Earth has led a lot of journalists to immediately jump to the conclusion that an alien civilisation is living there. Most accounts seem to suggest that it has five times the mass of Earth, making gravity a major factor, and that it orbits a red dwarf star - meaning that in order to be warm enough to have any kind of liquid water, it will need to be very close, subjecting its surface to the regular and intense solar flares that red dwarfs are famous for. I would be very surprised if anything other than basic single-celled organisms are living there, and as we can't even make up our minds on if there is life on Mars or not, I wouldn't think much about it for a while. For all we know, it may not even have an atmosphere.

Sedna is a tiny block of rock a bit further out than pluto. The new planet is 581C
