Document Summary

William herschel was cataloguing stars to look for stellar parallax when he discovered uranus. Hershel was particularly suited for discovering planets because he built the largest telescope of his time. 1)the star-like object increased in size when he increased his telescope magnification (suggests that it was not a star; stars always appear point-like to us regardless of the maginifcagtion) 2) he found that uranus have moved night to night relative to the stars. Uranus had a near circular orbit which would make it a planet, a comet would have an elliptical orbit. When kepler observed the large gap between mars and jupiter, he proposed: it contains an undiscovered planet.
