When the Earth passes directly between the Sun and Mars, the Earth and Mars are closest to each other. If Mars is 1.52 AU from the Sun and there are 1.5 x 108 km in 1 AU, how many times will the width of
the U.S. (2,530 miles) fit end-to-end between Mars and Earth?

Part 1 of 4
Mars is 1.52 AU from the Sun. How many times further away from the Sun is Mars than the Earth? (The distances in AU are relative to the distance between the Sun and the Earth, so however many AU a
planet is away from the Sun is how many times farther it is from Sun than Earth.)
1.52✔
1.52 times further away
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.
One year on Planet AAA is 5 time the length of one earth year and it orbits its sun at an
average distance 4.38 AU. Planet ZZZ orbits the same sun at an average distance of
2.53 AU. Determine the length of one year on Planet ZZZ in earth days.

At one point in the planet's orbit, called periapsis, it passes much closer to the star. Which of the following statements about periapsis is true? The planet's orbital period becomes shorter after every periapsis. The planet's orbital period becomes longer after every periapsis. The planet orbits with a slower speed during periapsis.

Use a mass of 1.99x10^30 kg to be 1 solar mass. For each of the different sun masses (as values of solar mass, aka 0.5 solar masses = 1x10^30 kg), as outlined in the lecture, calculate the period of the earth's orbit in days using Kepler's law for circular orbits (I double-checked it with these values and it works) and also calculate the corresponding orbital velocity of the earth. Questions: 1.) Using these values, and 6x10^24 kg for the mass of the earth, what is the strength of the gravitational force between the earth and the sun? 2.) If the earth were twice as far from the sun, what would be its period of orbit? 3.) Mars orbits the sun at a distance of 2.18x10^11 meters.

- Question 5 pleasearrow_forwardLet's assume that the planet was originally orbiting around something with the mass of our Sun (and thus the mass of the planet is negligible). Now we will examine the case where the planet orbits a star with 8 times the mass of our Sun, but we will say that the dates listed in the diagram above are still accurate for indicating the planet's position as it orbits the new star. What is ratio of the size of the semimajor axis of the planet in this case compared to the original (aka how many times larger {ratio greater than 1} or smaller {ratio less than 1} is the new semimajor axis than the old one)?arrow_forwardHow would you solve this problem??arrow_forward
