Imagine you are a travel agent in the next century. An eccentric billionaire asks you to arrange a “Guinness Book of Solar System Records” kind of tour. Where would you direct him to find the following (use this chapter and Appendix F and Appendix G):
A. the least-dense planet
B. the densest planet
C. the largest moon in the solar system
D. excluding the jovian planets, the planet where you would weigh the most on its surface (Hint:Weight is directly proportional to surface gravity.)
E. the smallest planet
F. the planet that takes the longest time to rotate
G. the planet that takes the shortest time to rotate
H. the planet with a diameter closest to Earth’s
I. the moon with the thickest atmosphere
J. the densest moon
K. the most massive moon

- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardIn Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2.

- 9 The discovery of Eris A Was not surprising, because the existence of a massive "Planet X" had been predicted nearly a century ago. B Was surprising, due to its "backwards" orbit around the Sun. C Was surprising, since we thought we knew about all large objects in the solar system. Was not surprising, because other Kuiper belt objects approaching the size of Pluto had already been discovered.

How far (in km) above the surface of the planet is it? (The mass of Venus is 4.87 x 1024 kg, and the radius of Venus is 6.05 x 103 km.) Part 1 of 3 The period of the orbiter's orbit can give us the speed at which the orbiter orbits the planet. We imagine the orbiter tracing a circle around the planet at a certain height, the speed is 2ar V = P Part 2 of 3 Next, we combine this with the circular velocity equation to determine the height above the planet's surface. GM V = 2ar GM Squaring both sides and solving for r gives the following equation. What is the exponent for r? GM Part 3 of 3 Congratulations!

- The gravity on Mars is about 38% that of Earth's gravity. Let's say some cargo has a mass of 15 kg here on Earth. First, what would be the weight of that cargo in kilograms on Mars?
