OUR SOLAR SYSTEM (CLASS-3)

By

 Hello students!!

Hope you are doing well.

So.... It's exam time and you are back to us 👀for learning. That's great!!!!!!

We will revise OUR SOLAR SYSTEM (FOR CLASS-3) here. Let's start summing up what you have learnt in your school text books 👇

  1. The solar system is a group of planets that orbit around a star called the Sun. 
  2. The Sun is actually a star, and it is the closest star to us. 
  3. The solar system also has other stars that are far away and cannot be seen with the naked eye.
  4. An orbit is the path that a celestial body takes around another body. 
  5. Planets orbit around stars, while moons orbit around planets.
  6. Orbits can be circular or elliptical in shape. 
  7. The shape of an orbit is determined by the gravitational pull of the two bodies involved. For example, the Moon orbits the Earth in an elliptical orbit, while the Earth orbits the Sun in a nearly circular orbit.
  8. Stars are giant balls of gas that produce light and heat through a process called nuclear fusion. The Sun is an example of a star. 
  9. Stars are much larger than planets and can be millions or billions of years old.
  10. Planets, on the other hand, are smaller than stars and do not produce their own light. They orbit around stars, like the planets in our solar system orbit around the Sun. 
  11. There are eight planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.



 


12. In addition to planets, there are other celestial bodies in our solar system, such as moons, asteroids, and comets. 
13. The main difference between stars and planets is that stars produce their own light, while planets reflect the light of their star. Stars also have their own heat source, while planets rely on their distance from their star to determine their temperature.
14. Constellations are groups of stars that form patterns or shapes in the sky. People have named these patterns after animals, objects, and mythical creatures. There are many constellations in the night sky, and they can be seen all year round.
15. Some common constellations and their shapes: (a) The Big Dipper: This constellation looks like a large spoon or dipper with a long handle. It is also called the Plough in some countries.
(b) Orion: This constellation looks like a man with a belt and a sword. It is one of the most recognizable constellations in the night sky.
  (c) Cassiopeia: This constellation looks like a "W" or "M" in the sky. It is named after a queen in Greek mythology.



Now, let's answer some questions:

Q1. What is a solar system?
Answer: A solar system is a group of planets that orbit around a star called the Sun.

Q2. What is the Sun?

Q5. How are constellations named?
Answer: Constellations are named after animals, objects, and mythical creatures.

Q6. What is the Big Dipper?
Answer: The Big Dipper is a constellation that looks like a large spoon or dipper with a long handle.

Q7. What is Orion?
Answer: Orion is a constellation that looks like a man with a belt and a sword.

Q8. Who is Cassiopeia named after?
Answer: Cassiopeia is named after a queen in Greek mythology.

Q9. What are stars made of?
Answer: Stars are made of gas, mostly hydrogen and helium.

Q10. How do planets differ from stars?
Answer: Planets are smaller than stars and do not produce their own light or heat.

Q11. How many planets are there in our solar system?
Answer: There are eight planets in our solar system.

Q12. What is the difference between a circular and elliptical orbit?
Answer: A circular orbit is perfectly round, while an elliptical orbit is more oval-shaped.

Q13. What determines the shape of an orbit?
Answer: The shape of an orbit is determined by the gravitational pull of the two bodies involved.


Let's revise the fill in the blanks:

1. Stars produce their own ________ and ________ through a process called nuclear fusion.
