In the figure below, Planet X is moving in a perfectly circular orbit around its companion star.The time between each position shown is exactly one month:
1. Write down Kepler’s second Law of planetary motion.2. Does the planet obey Kepler’s second law? How do you know?3. If you carefully watched this planet during the entire orbit, would its speed be increasing, decreasing, orstaying the same? How do you know?
Explain the geocentric view of the universe.
Use the circumference and speed to figure out how long the Sun takes to go once around the Galaxy (the Sun's period, sometimes called the "galactic year.") Give your answer in Earth years. Be careful with your units.

- Is the ecliptic the same thing as the celestial equator? Explain.arrow_forwardSuppose you are on a strange planet and observe, at night, that the stars do not rise and set, but circle parallel to the horizon. Next, you walk in a constant direction for 8000 miles, and at your new location on the planet, you find that all stars rise straight up in the east and set straight down in the west, perpendicular to the horizon. How could you determine the circumference of the planet without any further observations?
