- Astronomers solved this puzzle when they observed a rare transit of Venus in front of the Sun (Figure 5). What could they learn about the planet’s atmosphere from this photo?If gas expands to fill all the space available to it, explain why the Earth's atmosphere doesn't drift off into space.Why is Mars red?
- On mars, the surface temperature can be 55 F What is this temperatures in Celsius scale? (Hint: T F =(9/5)T C +32)Out of the inner planets in the solar system (Mercury, Venus and Mar) which do you think is the most likely to be colonized? Explain why?Saturn is even further at 1434X109m from the sun. Calculate the approximate strength of the greenhouse effect on Jupiter. The observed surface temperature is 133K, the albedo is 0.47, the solar constant is 15W/m2.
