I find it extremely funny that they talk like that these earth like planets that they hope to find someday wouldn't already be inhabited. Then what are they going to do. Invade and start a war? Yeah probably.

I net they've already found some. In all likelyhood, all you will hear about are the ones that are uninhabitable... Keplaer has to find something right?

I could have sworn that they a while back found a few planets much smaller than Earth even approaching dwarf planet size but this is truly a celebration. Planets do outnumber stars by many times interestingly. Thank you for this.

@ignaciojork - One light-year = 9,460,730,472,580,800 metres. So you need to multiply that figure by 950. It will take 17,500 years to travel one light-year at 61,200km/h, or 17km/s. When we learn how to travel at 10 trillion kilometres per hour, we can get there in under 40 days. :-)
