Tutorial

Our Solar System

 

Our solar system is made up of the Sun, four rocky planets (the inner, or nearest to the sun), four large, gas planets, the astroid belt, the Kuiper Belt, the Oort Cloud, and countless comets and other flying debris.  Until just a few years ago, we had another, very small, rocky planet called Pluto.  Pluto orbited at the very edge of our solar system, and was very difficult to see - even with the space-based Hubble telescope.  But now we finally have a close up look at our distant neighbor.

In the next few slides, read about the fascinating story of the planet Pluto.  When you are done, please complete the quiz.

NASA Probes

NASA has been sending probes to explore planets in our solar system since the 1970's, and has finally had a probe arrive at Pluto.  Pluto was originally discovered in 1930 by Clyde Tombaugh, but even from the start, Pluto stood out as an unusual planet.  Click on the link above the picture to read about the history of the discovery of Pluto.

The Big Question

In your own words, write a 1-2 page paper on why it is important that we sent a probe to Pluto, why we should explore the solar system or if it is waste of time and money, and what we hope to learn from this exploration.
