Kind: captions Language: en you know we never know any night it could be the night that we actually find it the skies clear though no that is awesome right there that's where it's up somewhere in the sky there is a single moderately faint object slowly moving go find that's the challenge it's gonna be a great night there's windy as we're supposed to I think yeah hopefully we don't break the till super is a huge telescope and also has this camera that's able to look at a big monster patch of sky what is this can use this is not good Konstantin almost always takes oxygen the trick to doing this right is to have to think as little as possible at 14,000 feet because thinking at 14,000 feet barely works [Music] Orbitz projected onto the night sky will appear in some swath but we don't know where inside that swath pine at night height we know its orbit pretty well we still argue about how well we know it Mike thinks we know it better than we know it I think I know it better than you know mike is delusional this is the map of the sky the two big red lines show us the expected path to Planet nine plan a nine is somewhere between these two spots in the sky you can see every place the telescope points is a little circle at the end of the day all that is going on is you just ultimately look for an object that move that's the goal let's go there's emerges basically you have to check every single star every single smudge that might be there and see if it's moving at all is in the same spot last night is the same spot tonight [Music] if it's going at the right speed that is but the day we find it telescopes everywhere it will be able to go look at it because once you know the coordinates to easy simple we are gonna study it and try to learn where it came from what it's made out of what does it tell us about the story of the solar system and that's what the real promise here you [Music]
