NATS 1745 Chapter Notes - Chapter 9-14: Brown Dwarf, Red Dwarf, Type Ia Supernova
Document Summary
Because no one in recorded history ever actually discovered a planet. Mars, jupiter and saturn can each be seen relatively easily with naked eye, and all were known to the ancients: what did some astronomers originally propose as the explanation for why uranus was.

Briefly describe (in 1 sentence) what this theory is used for. French mathematician proposed that an undetected eighth planet might be perturbing. Briefly describe (in 1 sentence) what this device allows astronomers to do. An ingenious mechanical optical device known as blink comparator led to the discovery of pluto.
