[[Beret Guy]] runs to wake up [[Cueball]], who is probably under the covers in bed, with his potentially middle of the night revelation that Humankind is discovering "{{w|exoplanet}}s" or planets that exist outside of our solar system. The indication is that these planets are habitable enough for humans, even if just for a visit.

Then Beret Guy takes it a bit further thinking that one of the countries on Earth could restart {{w|Project Orion (nuclear propulsion)|Project Orion}}. As Beret suggests, Project Orion was an early project to come up with a spacecraft that would ride the shockwave from a series of nuclear bombs it dropped in order to travel very, very fast. However, the one major downside of Project Orion was the fallout that the launching of any such craft would present on Earth. One could try to boost the Orion spacecraft into orbit with conventional rockets, but Orion spacecraft are heavy being composed of giant pusher plates and rows upon rows of nuclear bombs, they are hard to lift. On top of this, the {{w|Nuclear Test Ban Treaty}} means that the craft would be flatly illegal to build and launch on Earth, no matter what you did. However, if an asteroid mining project were to be started, the Orion drive spacecraft, the nuclear bombs, and all the infrastructure needed to man, build, and crew it could all be built safely in space, well away from the Earth's fragile biosphere, where little harm could be done. Some commercial spaceflight programs are interested in starting asteroid mining in the future, even now For Example: http://www.planetaryresources.com.

As Beret suggests, Project Orion was an early project to come up with a spacecraft that would ride the shockwave from a series of nuclear bombs it dropped in order to travel very, very fast. However, the one major downside of Project Orion was the massive degree of fallout that the launching of any such craft would present on Earth.

In summary, Beret is very excited that we can see (with the Hubble telescope and other earth-bound telescopes) and find exoplanets. Then with some advances in space technology we can create nuclear propulsion in space to reach these planets, and it will all be happening quite possibly within a few decades. He is thus worried that Cueball will miss all of this ongoing excitement.
+
Beret Guy references {{w|Stargate Atlantis}} when he mentions "City-Ships" as the city-ship Atlantis was the basis for the show. The city-ships on Stargate Atlantis are about the size of Manhattan.
  
Cueball would just rather snooze, as he is not impressed. Beret Guy gives him only one snooze because as is apparent in the title text he is afraid that Cueball will be be left behind if he snoozes too long! Giving the fact that he just stated that it may take hundreds of years this is of course silly, but fits well with Beret Guy's behavior.

Exoplanets have been discovered starting in 1996, but there are still only a few confirmed {{w|List of habitable planet candidates|planet candidates}} in the habitable zone at a distant star. This did change fast after that time since new ways of finding planets are created — see [[1071: Exoplanets]], which was posted with the same title. At that point, there were exactly 786 Exoplanets confirmed — the number of this comic - probably not a coincidence when it comes to [[Randall]].

It was the first time Randall released a comic with the exact same name as a previous comic. Since then he has done so [[:Category:Comics sharing name|a few times]]. When the next exoplanet comic was released it caused problems on xkcd as the title of the image file were the same for the two comics. This was resolved by renaming this comics image by adding the year 2010 to the title, the year of its released, two years before the next one.
 
 
 
'''Note:''' Cueball is never really visible in this comic, and the last image only shows a face. Given that all characters without a beard has the same face, this could have been any character, including one with a hat (which could be lying on the bed stand next to the bed) or hair (although the comic's official transcript refers to this person as "bed man", meaning it is not [[Megan]] or some other female character). As it is easier to explain the comic using Cueball's name, and given that he is the usual guy to draw when no features is needed, it still makes sense to call him Cueball in this comic.
