Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth.
