प्रश्न

In our solar system, the inter-planetary region has chunks of matter (much smaller in size compared to planets) called asteroids. They ______.

विकल्प

  • will not move around the sun since they have very small masses compared to sun.

  • will move in an irregular way because of their small masses and will drift away into outer space.

  • will move around the sun in closed orbits but not obey Kepler’s laws.

  • will move in orbits like planets and obey Kepler’s laws.

उत्तर

In our solar system, the inter-planetary region has chunks of matter (much smaller in size compared to planets) called asteroids. They will move in orbits like planets and obey Kepler’s laws.

Explanation:

Because as we know asteroids move in orbits like planet which follows Kepler’s law as they act upon central gravitational forces.
