Distant Dwarf Planet has No Atmosphere

Posted November 23, 2012 5:26 PM

From MSN:

Astronomers say Pluto's icy, more distant sister seems even more alien than thought because it doesn't have an atmosphere.

Scientists gained that bit of new knowledge about the dwarf planet Makemake by measuring light from data gathered by several large telescopes. Researchers report in the journal Nature that the small planet may simply have some pockets of atmosphere from methane ice turning into gas.

Makemake is one of four dwarf planets in our solar system beyond Neptune. It was discovered in 2005.

It is in our solar system, beyond Neptune.

Much closer than that. The "Golden Coral" restaurant is just down town.

Wow, that is the shortest article I've ever seen in a CR4 link. The entire article is what I thought was the CR4 teaser. There is much more information on Makemake at Wikipedia, including how they measured the lack of an atmosphere in April last year. I guess science news travels slowly on the internet. How ironic.

Makemake has an atmosphere. Go there and you will be standing on it.

At -243.2 oC and 2/3 the size of Pluto it is pretty much given that unbonded hydrogen and the Helium will escape and most everything else will turn solid.

I guess my question is why is this news? Now if it had an atmosphere, that would be news.

Only the time frame surprises me.
