If a planet with 1.5 times the mass of Earth was traveling in Earth's orbit, what would it's period be? I am told by my professor the answer is "the same period as earth 365.25 days." I do not understand why or how to achieve it mathematically.
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 satellite is in orbit around Earth at a height of 120 km above Earth’s surface. Find the orbital speed of the satellite. (Mass of the earth is 6*1024 kg and the radius of Earth is 6371 km)
An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 9.00 m/s^2. Determine the orbital period of the satellite. I_o, a satellite of Jupiter, has an orbital period of 1.77 days and an orbital radius of 4.22 times 10^5 km. From these data, determine the mass of Jupiter. A minimum-energy transfer orbit to an outer planet consists of putting a spacecraft on an elliptical trajectory with the departure planet corresponding...
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?
Question 6 (8 points) 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. What is the orbital radius of this planet in AU, where 1 AU is the earth-sun distance
Problem 1 Planetary Orbits Consider the two-body problem for a planet-star system. The planet, of mass m, is initially in a circular orbit of radius r and angular speed w about the star, of mass M. (i) What is the gravitational potential energy of the system, U? What is the kinetic energy of the planet, K? What is the total energy of the system, E = K +U? (ii) The star suddenly loses half of its mass, M + M/2....
A planet of mass m=2.95×1024 kg is orbiting in a circular path a star of mass M=1.75×1029 kg . The radius of the orbit is R=6.25×107 km . What is the orbital period (in Earth days) of the planet Tplanet ?
The radius of a planet is three times that of Earth and its mass is nine times that of Esrth. The acceleration due to gravity on this planet is
