Consider the following statements regarding celestial bodies: 1. All celestial bodies emit their own heat and light in large amounts. 2. Stars are celestial bodies made up of gases. 3. The Sun is a celestial body that reflects the light of other stars. Which of the statements given above is/are correct?

The correct option is (b) 2 only. Explanation Celestial bodies encompass all natural objects located outside of Earth's atmosphere, such as the Sun, Moon, stars, and planets. A fundamental distinction exists between those that generate their own energy and those that do not. - Statement 1 is Incorrect: Not all celestial bodies emit their own heat and light. While stars emit heat and light in large amounts, other celestial bodies such as planets, satellites (moons), asteroids, and meteoroids do not possess their own heat and light. They are visible primarily because they reflect the light of stars. - Statement 2 is Correct: Stars are celestial bodies that are typically very large and hot. They are composed primarily of gases (such as hydrogen and helium). Due to nuclear fusion reactions occurring in their cores, they generate and emit their own heat and light. - Statement 3 is Incorrect: The Sun is a star. It is a self-luminous body made of hot gases. It generates its own heat and light through nuclear fusion and serves as the primary source of energy for the Solar System. It does not reflect the light of other stars. Key Takeaway: Stars are luminous celestial bodies made of gases that emit their own heat and light, whereas planets and satellites are non-luminous bodies that rely on reflected light.

Solution

The correct option is (b) 2 only.

Explanation

Celestial bodies encompass all natural objects located outside of Earth's atmosphere, such as the Sun, Moon, stars, and planets. A fundamental distinction exists between those that generate their own energy and those that do not.

Statement 1 is Incorrect: Not all celestial bodies emit their own heat and light. While stars emit heat and light in large amounts, other celestial bodies such as planets, satellites (moons), asteroids, and meteoroids do not possess their own heat and light. They are visible primarily because they reflect the light of stars.
Statement 2 is Correct: Stars are celestial bodies that are typically very large and hot. They are composed primarily of gases (such as hydrogen and helium). Due to nuclear fusion reactions occurring in their cores, they generate and emit their own heat and light.
Statement 3 is Incorrect: The Sun is a star. It is a self-luminous body made of hot gases. It generates its own heat and light through nuclear fusion and serves as the primary source of energy for the Solar System. It does not reflect the light of other stars.

Key Takeaway: Stars are luminous celestial bodies made of gases that emit their own heat and light, whereas planets and satellites are non-luminous bodies that rely on reflected light.
