Question 6 (8 points) A spherical planet has 12 times the earth's mass and has three...
A spherical planet has 12 times the earth's mass and has three times the earth's radius. It orbits a star with 5 times the sun's mass with an orbital period of 7 years. If an alien spaceship weighs 180 Zorgs on the alien planet (where a Zorg is the alien unit of weight), then what is the weight of their spaceship on earth in Zorgs?
Planet X has 20 times the mass of the earth and 3 times the earth's radius. It orbits star Y at a distance of 8 AU, where 1 AU is the earth-sun distance. Star Y has twice the mass of our sun. (a) What is the orbital period of Planet X in years? (b) An astronaut has an earth weight of 120 lbs. What is her weight on the surface of planet X?
A planet with twice the mass of the Earth orbits a star that is 2/3 the mass of the Sun. The orbital radius of the planet around the star is 4.5X10^12m. What is the orbital period of the planet?
A planet is discovered to orbit around a star in the galaxy Andromeda, with the same orbital diameter as the Earth around our Sun. If that star has 4 times the mass of our Sun, what will the period of revolution of that new planet be, compared to the Earth's orb o One-fourth as much o One-half as much Twice as much A. Four times much The average distance from the Earth to the Sun is defined as one "astronomical...
6. Using Nowton's version of Kepler's Third Law (15 points). a) (5pt) Compute the semimajor the mass of the Sun from the fact that the Earth's orbital period is 1 year and axis is 1 AU. Assume that the mass of the Earth is much smaller than the mass of the Sun. Is this assumption justified? pt) Compute the orbital period of a cubesat orbiting the Earth at an altitude of 400 km above the Earth's surface. c) (5pt) Estimate...
In Lecture 4, we discussed Kepler’s third law relatingthe orbital period of a planet (p) to the semi-major axis (orbital distance, a) of its orbit(p2= a3). We can apply this law as long the object orbits the Sun or another object of the same mass, and the units of orbital period are in (Earth) years and the orbital distance is in Astronomical Units(AU). [1AU is equal to the distance between the Earth and the Sun]. [Note: Newton extended this law...
1. An object is orbiting around the planet Quakers with an average distance of 75,000 km. The value of "k" - 6.9 x 10" (units of days and km). What is the orbital period in days? 2. If an object has an orbital period of 85 years and is at an average distance of 24 AU from the object it orbits, what is the value of "k"? 3. If an object is orbiting the Sun with an orbital period of...
Astronomers discover an exoplanet (a planet of a star other than the Sun) that has an orbital period of 3.97 Earth years in its circular orbit around its sun, which is a star with a measured mass of 3.41 times 10^30 kg. Find the radius of the exoplanet's orbit. _____ m
QUESTION 4 1 points Using Newton's revision of Kepler's third law, calculate the mass (in solar masses) of a star where an Earth like planet orbits it with a semi-major axis of 9 AU and a period of 4.87 Earth years. Recall that for an Earth-like planet, its mass is negligible compared to that of the star. Report your answer to two decimal places
