It has a 10-Earth-year Year, is about 2.5 AU from its Red Dwarf sun, and is about 5 times the mass of our own planet Earth.

However, it's exciting because more and more terrestrial planets are being discovered. In a few years we might even be able to find real Earth-like planets, as in oceans, organic life, etc.

I really don't understand how a planet with surface temperatures of -220ºC could be classified as 'earth-like'. The only similarity between these planets are that they are both made out of rock.
In vino veritas.

Maybe it's more like Uranus.

I wasted my 1,000th post on this.

Most earth-like yet. I think the others have mostly been gas giants.

I buy the idea that if we find some of them planets close enough to the conditions that will allow life processes to happen may be we could even seed life into it or engineer it towards sustaining life eventually.

Heck, I think it will be cool to seed life all over the cosmos if we can... why not?

It's Earth-like as much as Venus or Mars are Earth-like. The planet is terrestrial, which is important, but most importantly it's within that buffer zone distance between Venus and Mars where a real Earth-like planet could form.

The only problem is that is sun isn't very hot and it doesn't have an atmosphere that we can detect. So it's bitter cold.
