In each case, describe what kind of protective gear they would have to carry, and what their chances for survival would be if their spacesuits ruptured.arrow_forwardWhy would a tourist brochure (of the future) describing the most dramatic natural sights of the giant planets have to be revised more often than one for the terrestrial planets?arrow_forwardWhy do small planets cool faster than large planets? Choose any two of the five Terrestrial worlds and calculate for each one the ratio of its surface area to its volume. Why is this ratio important? (Hint: Does this ratio have anything to do with the ability of a planet to lose internal heat?) (Note: The surface area of a sphere is 4r2, and the volume of a sphere is 43r3.)arrow_forward

How many times fainter would Venus look from a distance of 1 pc? What would its apparent magnitude be? Assume Venus has the same illumination phase from your new vantage point.

You listen for the probe when Mercury is moving away from Earth at its full orbital velocity of 48 km/s around the Sun. What wavelength would have to tune your radio telescope to detect that signal? (Hint: Use the Doppler shift formula, Eq. 7-3.) (Note: The speed of light is 3.0 105 km/s.)arrow_forwardThe runaway greenhouse effect and its inverse, the runaway refrigerator effect, have led to harsh, uninhabitable conditions on Venus and Mars.
