The linear speed of a planet around the sun is not constant in its orbit. Comment.

The orbital speed of a planet around the sun depends on the mass of the planet -is this statement true or false ?

The period of revolution of a planet around the sun in a circular orbit is T. If a similar planet is revolving in a circular orbit of the same radius around the sun with its mass twice as that of planet, its period of revolution would be

A planet is moving around the sun in an elliptical orbit. Its speed is

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

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

The period of a planet around Sun is 27 times that of Earth. The ratio of radius if planet's orbit to the radius of Earth's orbit is:

Suppose there existed a planet that went around the sun twice as fast as the earth. What would be its orbital size as compared to that of the earth ?
