  • 23. Planets
    A planet is a celestial body that orbits a star . All the planets are spherical in shape . They are non-luminious , i.e. , they do not produce light of their own . Instead , they reflect the light of the Sun that falls on them . Every planet spins on its own axis is called rotation . One complete movement around the Sun is called a revolution or planet-year.
  • 24. Mercury
  • 25. Mercury , the planet near the Sun and is the second smallest planet in the solar system , only slightly larger than the Earth’s Moon . Mercury’s surface is covered with craters . This tiny planet does not have any rings or Moon .
