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?

6. We’ve learned that incredibly intelligent (and superior) aliens from the planet Splorg are planning toinvade the Earth. However, they have first decided to determine how smart we humans are. If theydeem us smart enough, they might reconsider their planned invasion. To evaluate our intelligence, theyhave asked us to get our Physics class to figure out at what radial distance they would need to orbit asatellite so that it always remained at the same location above the Splorigian equator (i.e. insplorgeosynchronous orbit). They also want to know what velocity they’d need their spacecraft toreach in order for it to escape the gravity of Splorg when the time comes to invade Earth. Here’s theinformation they gave us: a day on Splorg lasts the equivalent of 31.7 hours. At the equator, Splorg hasa circumference of 54,660 km. Finally, they’ve told us that it takes a 2 kg mass exactly 0.56 s to fall adistance of 2 m at the surface of Splorg

The constraint for a Sun-synchronous and repeat ground-track orbit is given by T 86, 400, where T is the orbital period in seconds, m the number of days and k the number of revolutions. Explain why this is, in fact, a constraint on the semi-major axis of the orbit. m
