Question 20 5 pts Imagine you've been taken to another planetary body (like a planet or moon) in our solar system, but you don't know which one. You're not allowed to look around at the ground, all you can do is to look at the starry sky. Which of the following things would be a good tip-off" that you're not on the Earth? The north and south celestial poles appear to be located in two of the constellations that we Earthlings call ecliptic (a.k.a. zodiac) constellations, The Sun and stars appear to go around the planetary body you're on in a period of about 24 hours. If you look carefully at the other planets, and compare their positions to the background stars, you'll notice that they sometimes appear to move backwards, i.e. westward, instead of their normal eastward motion The Sun appears to make one full 360-degree trip around the sky, in front of the ecliptic (a.k.a. zodiac') constellations in one Earth year.
