Chapter 13, Problem 51EAP
Planet Around 51 Pegasi. The star 51 Pegasi has about the same mass and luminosity as our Sun and is orbited by a planet with an orbital period of 4.23 days and mass estimated to be 0.6 times the mass of Jupiter.
Use Kepler’s third law to calculate the planet’s average distance (semimajor axis) from its star. (Hint: Because the mass of 51 Pegasi is about the same as the mass of our Sun, you can use Kepler’s third law in its original form,
- [Section 3.3]. Be sure to convert the period into years before using this equation.)
- Suppose the planet reflects 15% of the incoming sunlight. Using Mathematical Insight 10.1, calculate its “no greenhouse” average temperature. How does this temperature compare to that of Earth?
- Repeat part b, but assume that the planet is covered in bright clouds that reflect 80% of the incoming sunlight.
- Based on your answers to parts b and c, do you think it is likely that the conditions on this planet could be conducive to life? Explain.

Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.
Two exoplanets, UCF1.01 and UCF1.02 are found revolving around the same star. The period of planet UCF1.01 is 4.8 days, and that of planet UCF1.02 is 5.2 days. If the average distance of planet A to the sun is 2,885.4 km, what is the average distance of planet B to the sun km? Please keep four digits after decimal points.
The star 51 Pegasi has about the same mass as ourSun. A planet discovered orbiting it has an orbital period of4.95 days. The mass of the planet is estimated to be 0.64 timesthe mass of Jupiter. Use Kepler’s third law to find the planet’saverage distance (semimajor axis) from its star.
