You can answer this question if you know (or look up) two other pieces of information. 1) What are the names of all the planets? 2) What are the names of the planets you can see with the naked eye? If you can't see it with the naked eye, it must have required a telescope to discover it. The planets are, in order from their distance from the Sun: Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto (yes, I still count Pluto as a planet). The naked-eye planets are: Mercury Venus Earth (duh, look down) Mars Jupiter Saturn That leaves Uranus, Neptune, and Pluto as the planets discovered by telescope. Unless your professor believes that Pluto is not a planet, in which case the answer is Uranus and Neptune. And actually, if you look up information on these planets, you'll learn that Neptune and Pluto were "discovered" by noticing that something was disturbing (the astronomers say "perturbing") the orbits of other planets. Based on the disturbance, the position of the object was calculated. Then people looked for the object, and found it. So was the planet only "discovered" when someone saw it with a telescope? Or was it "discovered" by perturbation analysis and only "verified" with a telescope? If your professor believes the second one, then that leaves Uranus as the only planet discovered by telescope.

Saturn was the first planet discovered to have rings. They were first observed by Galileo Galilei in 1610 through his telescope.
Does the planet Kepler really exist?
There is a bit of confusion here. Kepler is not the name of a planet but of a space telescope used to discover planets in other solar systems. Planets discovered with this telescope are given designations such as Kepler-22b. This telescope has been used to discovered hundreds of planets.
