Answer the following questions after lookin at the picture below:

1. In terms of the properties measured by the graphs, which properties should we most be looking for in a candidate planet? Which are most important, and why?

2. Are planets missing from the graph that might be better still?

3. Which graph or combination of graphs would help you make the best decisions?

Earth compounds 0.6 super-dense shot Jupiter 6 O. Venus 0.4 4 terrestrial planets (rock and metal) water worlds" Kepler 16 Tatooine 0.2 first known planet orbiting binary star 2 . . metal-rich terrestrial planets "super-Earths" 0 0 1000 planetary mass (Earth units) Kepler 11f Very low mass planet, member of a 6-planet system Kepler 10b very dense super-Earth COROT 7b rocky super-Earth probably molten GJ 1214b possible water world

Explanation / Answer

Answer:1

As the graphs represents the planet's radius and orbital eccentricity therefore planet mass would be one of the important property which should be consider. Because gravity of planet depend upon its mass, moreover its speed of rotation, eccentricity would be effect by its mass.

Answer:2

No, as we can see the earth and Venus are away from graph line but they are moving planets. However, their orbital eccentricity are almost zero.

Answer:3

Both the first two graphs helps us to decide the importance of properties of planets, both graph shows the planet's radius and orbital eccentricity.
