Question:
For the previous planet and star (with a luminosity = 0.041
solar luminosity), assuming a
circular orbit, what would be the distance from the star such that
the planet’s surface
temperature is 280 K (no atmosphere or greenhouse effect to worry
about)? What are the
orbital period and circular velocity of the planet? What is the
circular velocity of the star (in
m/s) that would be measured with the Doppler shif
