Get started for freeUse the Stamy Night Enthusiast TM program to examine the Jovian planets Jupiter, Saturn, Uranus, and Neptune. Select each of these planets from the Solar System submenu in the Favourites menu. If you desire, you can remove the image of the astronaut's feet by selecting Feet in the View menu. Position the mouse cursor over the planet and click and drag the image to examine the planet from different views. Describe each planet's appearance. Which has the greatest color contrast in its cloud tops? Which has the least color contrast? What can you say about the thickness of Saturn's rings compared to their diameter?
What is an asteroid? What is a trans-Neptunian object? In what ways are these minor members of the solar system like or unlike the planets?
Use the Deep Space Explorer \({ }^{T M}\) program to examine the Jovian planets Jupiter, Saturn, Uranus, and Neptune. In the left-hand part of the window, under the heading Solar System select Explore. Then click on the name of each planet to view it in detail. You can zoom in and zoom out using the buttons at the upper left of the window (an upward-pointing triangle and a downward- pointing triangle). You can also rotate the planet by putting the mouse cursor over the image of the planet or asteroid, holding down the mouse button, and moving the mouse. (On a two-button mouse, hold down the left mouse button.) Describe each planet's appearance. Which has the greatest color contrast in its cloudtops? Which has the least color contrast? What can you say about the thickness of Saturn's rings compared to their diameter?
What are the asteroid belt, the Kuiper belt, and the Oort cloud? Where are they located? How do the objects found in these three regions compare?
