The planet neptune travels around the sun with a period of 165 yr. What is the radius of the orbit approximately, if the orbitt is considered as circular ?

Calculate the period of revolution of Neptune around the sun, given that diameter of its orbit is 30 times the diameter of earth's orbit around the sun, both orbits being assumed to be circular.

The period of a planet around sun is 27 times that of earth the ratio of radius of planet orbit to the radius of eath ' orbit is

Calculate the period of revolution of the neptune around the sun, given that diameter of its orbit is 30 times the diameter of the earth's orbit around the sun. Assume both the orbits to he circular.

The period of revolution(T) of a planet moving round the sun in a circular orbit depends upon the radius (r) of the orbit, mass (M) of the sun and the gravitation constant (G). Then T is proportioni of r^(a) . The value of a is

What is the usual shape of orbits of planets around the sun ?

Asteroids revolve around the sun between the orbits of the planets :

A planet revolves around the sun with half as fast as the earth revolves around the sun. Determine its orbital size as compared to that of the earth.

How will you weight the sun, i.e. estimate its mass ? You will need to know the period of one of its planets and the radius of the planetary orbit. The mean orbit radius of the earth around the sun is 1.5 xx 10^(8)km , then the mass of the sun would be calculated as
