The Saturn is about six times farther from the Sun than The Mars Which planet has
(a) the greater period of revolution
(b) the greater orbital speed and (c )the greater angular speed ?

Which planet has a greater mass than all the other planets put together?

The distance of planet Jupiter from the Sun is 5.2 times that of the earth. Find the period of revolution of Jupiter around the Sun.

Two planets of equal mass orbit a much massive star (figure). Planet m_(1) moves in circular orbit of radius 1 xx 10^(8) km with period 2 yr . Planet m_(2) moves in an elliptical orbit with closed distance r_(1) = 1 xx 10^(8) km and farthest distance r_(2) = 1.8 xx 10^(8) km , as shows. (a) Using the fact that the mean radius of an elliptical orbit is the length of the semi-major axis, find the period of m_(2)'s orbit. (b) Which planet has the greater speed at point P ? Which has the greater total energy? (c ) Compare the speed of planet m_(2) at P with that at A .

The distance of the planet Jupiter from the Sun is 5.2 times that of the Earth. Find the period of Jupiter's revolution around the Sun.

Which is greater -rms speed or mean velocity?

If a and b are the nearest and farthest distances of a planet from the sun and the planet is revolving in an elliptical orbit, then square of the time period of revolution of that planets is directly proportional to

A planet of mass m is moving in an elliptical orbit about the sun (mass of sun = M). The maximum and minimum distances of the planet from the sun are r_(1) and r_(2) respectively. The period of revolution of the planet wil be proportional to :
