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.
What do we mean by apparent retrograde motion of planets? Why was it difficult for ancient astronomers to explain? How do we explain it today?
I am stuck on where to start with this question...
2. a. For two moons, (Moon A and Moon B) with the same mass, both in circular orbits about Mars, how many times more quickly or slowly is Moon B moving along its orbit if it 9 times farther from Mars' center than Moon A?
b. Now if Moon A is 4 times more massive that Moon B, how much faster or slower will Moon B's orbital velocity be (relative to that of Moon A)?

- Using Kepler’s Third Law (r3 = MT2 where M is the mass of the central star) find the orbital radius in astronomical units of this planet. M = 1.5 times the mass of the sun. Remember to convert days to years using 365.25 as the length of a year in days. Key Points to know: - The semimajor axis of the planet in AU is r = 0.0379 AU - The circumference of the orbit is l = 3.562 x 10^10 m - The orbital velocity in m/s is v = 1.874 x 10^5 m/s Questions that need to be answered: - With that orbital velocity, the radius of the orbit in meters, find the centripetal acceleration of our exoplanet: - Knowing the acceleration that our planet experiences, calculate the force that the host star exerts on the planet: - Knowing the force on the planet, the orbital radius, and the mass of the parent star, use the equation for gravitational force to find the mass of our planet (m2).
