Study Notes
Celestial Bodies
- Celestial bodies are objects in the night sky, including the moon, stars, and other shining objects.
- The moon appears at different times, in different shapes and positions, and can only be seen in its full form once a month (Full Moon or Poornima).
- A fortnight later, the moon is not visible at all (New Moon or Amavasya).
- The sun's bright light makes it difficult to see celestial bodies during the day.
Stars and the Sun
- Celestial bodies that are very big and hot, made up of gases, are called stars.
- Stars emit their own heat and light in large amounts.
- The sun is a star, and countless twinkling stars in the night sky are similar to the sun.
- Stars appear tiny because they are very far from us.
Constellations and the North Star
- Constellations are patterns formed by different groups of stars.
- The Saptarishi (Big Bear) is one such constellation, with seven stars that form part of the Ursa Major constellation.
- The North Star (Pole Star) indicates the north direction and remains in the same position in the sky.
- The North Star can be located using the Saptarishi constellation.
Planets and Satellites
- Celestial bodies that do not have their own heat and light, but are lit by the light of stars, are called planets.
- The word "planet" comes from the Greek word "Planetai," meaning "wanderers."
- The Earth is a planet, getting its heat and light from the sun.
- Satellites, like the moon, orbit around planets and are lit by the light of stars.
