Kepler's second law states that a planet speeds up as it gets closer to the Sun. The image below shows a planet in its counterclockwise orbit around the Sun. The orbit is highlighted in red. Which of the following statements is true?

According to the 2nd planetary law motion contributed by Kepler, the revolving speed of a planet around the sun in an elliptical orbit gradually increases as it approaches the sun and subsequently decreases as it goes away from the sun. From this planetary motion around the sun, it has been concluded that the radius vector originating from the sun and extending to the planets, covers an equal amount of areas in an equal amount of time.

This changing speed of planets occurs due to the effect of the sun's gravitational force of attraction. A planet experiences strong gravitational force when it comes near to the sun, as a result of which the revolving speed increases. Whereas its speed decreases as it moves away from the sun, experiencing a weaker gravitational force.

Thus, the revolving speed of the planet gradually will increase as it is coming closer to the sun.

Hence, the correct answer is option (1).
