A collection of small, icy bodies are found in the _______________ orbiting in the outer fringes of our Solar System
 
  Fill in the blank(s) with correct word

Question 2

Explain why it would be better to obtain stellar parallax for stars if we could observe from the planet Mars instead of the Earth.
 
  What will be an ideal response?

Answer to Question 1

Kuiper belt

Answer to Question 2

Observing from Mars would give us a longer baseline in order to measure parallax angles. In addition, the blurring caused by Earth's atmosphere smears star images. Even when astronomers average together many observations, they cannot measure parallax from an Earth observatory with uncertainty greater than about 0.02 arc second from Earth. Measuring parallaxes from Marshabove the blurring effects of Earth's atmospherewould yield a more accurate estimation.
