Statement-1: In its elliptical orbit around the sun, the earth is closer to the sun during summer then during winter in northen hemisphere
Statement-2:The angular momentum of the earth about the sun is conserved.

Earth completes one orbit around the sun is

If r is the distance between the Earth and the Sun. Then, angular momentum of the Earth around the sun is proportional to

r denotes the distance between the sun and the earth. Assume that the earth moves around the sun in a circular orbit of radius r. The angular momentum of the earth around the sun is proportional to

The angular velocity of earth around the sun increases when it comes closer to the sun. Why ?

A planet of mass $m$ revolves in elliptical orbit around the sun of mass $M$ so that its maximum and minimum distance from the sun equal to $r_a$ and $r_p$ respectively. Find the angular momentum of this planet relative to the sun.

When the Earth in its orbit is at the greatest distance from the Sun, it is at its?

A comet is in highly elliptical orbit around the Sun. The period of the comet's orbit is $90$ days. Some statements are given regarding the collision between the comet and the earth. Mark the correct statement. [Mass of the Sun $=2\times {10}^{30}kg$, mean distance between the earth and the Sun $=1.5\times {10}^{11}m$.]

If earth is revolving in elliptical orbit around sun, then which of the following quantity remains constant w.r.t.

Find the component statements of the following compound statement: The earth is round or the sun is cold.

A comet of mass m moves in a highly elliptical orbit around the sun of mass M the maximum and minium distacne of the comet from the centre of the sun are $r_1$ and $r_2$ respectively the magnitude of angular momentum of the comet with respect to the centre of sun is
