2016 ED85 Asteroid orbit 0.08 from the earth'd orbit, how many meters away is the orbit from earth?

A planet had a gravitational field at its surface if 7.6 m/s2 the mass of the planet us 4.5 x 10^24 What is tth planets force of gravity on a 70 kg objectt on the surface

Two planets orbit a star. You can ignore the gravitational interactions between the planets. Planet 1 has orbital radius r₁, and planet 2 has r₂ = 4r₁ Planet 1 orbits with period T₁ Planet 2 orbits with period A. T₂ = -1/T₁ B. T₂=2T₁ C. T₂ = 4T₁ D. T₂=8T₁

Satellite in Orbit 12 3? 5 6 Scientists want to place a 4100 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.5 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem: mmars = 6.4191 x 1023 kg "mars = 3.397 x 106 m G = 6.67428 x 10-11 N-m?/kg? 1) What is the force of attraction between Mars and the satellite? Submit + 2) What speed should the satellite have to be in a perfectly circular orbit? m/s Submit 3) How much time does it take the satellite to complete one revolution? hrs Submit 4) Which of the following quantities would change the speed the satellite needs to orbit at? O the mass of the satellite O the mass of the planet O the radius of the orbit Submit 5) What should the radius of the orbit be (measured from the center of Mars), if we want the satellite to take 8 times longer to complete one full revolution of its orbit? m Submit

The moon on Mars Phobos ( Fear) and Deimos ( Terror) are very close to the planet compared to Earth's Moon. Their orbital radii are 9,376 km and 23,463.2 km respectively. A) what is the orbital speed of Phobos to that of Deimos? B) If the period of Phobos orbits 7hr 39.2 min, what is the mass of Mars? C) Calculate the orbital period of Deimos.

8.) The Martian moon Deimos has an almost perfectly circular orbit, completed once every 30.3 hours at a speed of 1.35 km/s. What is the radius of its orbit? The radius of Mars is 3.39 x 106 m. What is its escape velocity? To what radius would Mars have to collapse to become a black hole?
