The Stars
Some celestial bodies are very big and hot. They are made up of gases. They have their own heat and light which they emit in large amounts. These celestial bodies are called stars. A star is a celestial object comprising a luminous plasma held together by its gravity
The star nearest to the earth is the Sun itself. The next nearest star is the Alpha Centuari or Proxima Centuari. This is at a distance of 4.3 light years from the earth. This means that we get the light from this star only 4.3 years after it gets emitted from it. We must remember that there are countless other stars whose light reaches us in a much longer time ranging from thousands of years to even millions and billions of years. In comparison takes about 8 minutes only for the light of the sun to reach the earth.
Which of the following are correct : (a) A star is a celestial object comprising a luminous plasma held together by its gravity. (b) The star nearest to the earth is the Sun itself. (c) The nearest star is the Alpha Centuari or Proxima Centuari. | |||
