Question

Fill in the blank
The Earth travels around the Sun in ……………………...

Answer 1

Hint: Earth is one of the eight planets of our solar system. Like every other planet, the Earth also revolves around the Sun owing to the gravitational pull of the Sun. This revolution or the movement is similar to the Moon orbiting the Earth.

Complete step by step answer:
The planet Earth is the third planet away from the Sun in the solar system. It has a wide surface area of 40,075 km at the parallel equator and a diameter of almost 12,756.3 km. The Sun is a star located at the very core of the solar system. The Sun consists of a diameter of about 1.392 million km. The Earth spins around itself as it revolves around the Sun.
According to the scientist Newton, we can contribute the factor of gravity to the movement of the Earth in an elliptical orbit, not in a circular orbit. Like the sun exerts a gravitational pull over the planets of the solar system, the planets also exert such pull on each other. This process of multiple gravitational forces acting together makes the Earth revolving in an elliptical orbit rather than a circular one. The difference in the position of Earth and Sun is around 147.46 million kilometers. For the Earth to take a single orbit, a complete one year is needed. The associated distance is around 149.6 million kilometers. The Earth revolves around the Sun at a speed of about 18.5 miles/sec (30 km/sec).
Hence, the Earth travels around the Sun in an elliptical orbit.

Note: According to Newton’s law of gravity, the gravitational forces that act between the planets and also among the sun and the planets determines the shape of the orbit the earth takes while revolving around the sun.
