Detailed explanation-1: -Answer: Correct option is 1-They are large bodies in space that orbits the sun. Explanation: The gravitationally bound system comprising the Sun and the asteroids that orbit it is known as the Solar System.
Detailed explanation-2: -It says a planet must do three things: It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.
Detailed explanation-3: -The Sun is still by far the most massive body in the Solar System . It contains more than 99.8% of all the system’s mass.
Detailed explanation-4: -They discovered that all the planets, including the Earth, actually orbit around the Sun. Not only did scientists discover that the simple fact that the planets orbit the Sun, they uncovered the underlying reasons for why.
