What is the most widely accepted theory for the formation of our Solar System?

Back

The Solar System formed by gravitational collapse of a gas-dust 'cloud'.

Front

What would happen to Earth if the gravitational force between it and the Sun were eliminated?

Back

Earth would move in a straight line in the direction it was heading at the moment the force was eliminated.

Front

Which planet has the most circular orbit in our Solar System?

Back

Venus has the most nearly circular orbit.

Front

What is the period of revolution for a planet that takes less than 40 days to orbit the Sun?

Back

The period of revolution is less than 40 days.

Front

Which celestial body is NOT part of our Solar System?

Back

Polaris is not included in our Solar System.

Front

Define gravitational collapse in the context of solar system formation.

Back

Gravitational collapse is the process by which a cloud of gas and dust contracts under its own gravity, leading to the formation of stars and planetary systems.

Front

What is the significance of the Big Bang in relation to the Solar System?

Back

The Big Bang is the event that created the universe, but the Solar System formed later from a gas-dust cloud.

Front

Explain the concept of orbital mechanics.

Back

Orbital mechanics is the study of the motion of objects in space under the influence of gravitational forces.

Front

What is the difference between a planet's revolution and rotation?

Back

Revolution is the movement of a planet around the Sun, while rotation is the spinning of a planet on its axis.

Front

What factors determine the shape of a planet's orbit?

Back

The shape of a planet's orbit is determined by its velocity, the mass of the Sun, and the gravitational forces acting on it.
