Assuming that earth and mars move in circular orbits around the sun, with the martian orbit being 1.52 times the orbital radius of the earth. The length of the martian year is days is

The planet Mars has two moons. Phobos and Delmos (i) phobos has period 7 hours, 39 minutes and an orbital radius of 9.4 xx 10^(3) km . Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being 1.52 times the orbital radius of the Earth. What is the length of the martian year in days? (G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))

A planet moving in a circular orbit around the sun at a distance, 4times theaverage distance of the earth from the sun will complete one revolution in

In equilibrium, Mars emits as much radiation as it absorbs. If mars orbits the sun with an orbital radius that is 1.5 times the orbital radius of the earth about the sun, what is the approximate atmospheric temperature of mars? Assume the atmospheric temperature of earth to be 253 K -

A satellite is moving in an orbit around the earth due to

Earth completes one orbit around the sun is

Assume that Earth is in circular orbit around the Sun with kinetic energy K and potential energy U, taken to be zero for infinite separation. Then, the relationship between K and U:

A satellite of Sun is in a circular orbit around the Sun, midway between the Suna and earth. Find the period of this satellite.

In adjoining figure earth goes around the sun in eliptical orbit on which point the orbital speed is maximum :
