**1. Definition of Celestial Body:**
A celestial body is any natural object that exists outside of Earth's atmosphere. These objects include planets, moons, asteroids, comets, stars, galaxies, and even dust particles.

**2. Earth as a Planet:**
Earth is the third planet from the Sun in our solar system. It is a terrestrial planet, meaning it is made up of rocky material and has a solid surface. Earth is spherical in shape and has a diameter of approximately 12,742 kilometers. It takes about 365.25 days for Earth to complete one orbit around the Sun.

**3. Earth's Place in the Solar System:**
The Solar System is composed of the Sun, eight planets, numerous moons, asteroids, and comets. Earth is one of these planets, and it orbits around the Sun along with other celestial bodies. It is located in the habitable zone, where conditions are suitable for the existence of liquid water, which is crucial for supporting life.

Earth also has a natural satellite called the Moon. The Moon is Earth's only known natural satellite and is the fifth-largest moon in the Solar System. It orbits around Earth and plays a significant role in our planet's various phenomena, including tides.

**5. Earth's Celestial Features:**
Earth possesses various celestial features, such as an atmosphere, which is a layer of gases surrounding the planet. The presence of an atmosphere enables weather patterns, protects living organisms from harmful radiation, and allows for the existence of water in its three states: solid, liquid, and gas.

**Conclusion:**
In conclusion, Earth is undoubtedly a celestial body. It is a planet that orbits around the Sun, has a solid surface, and is part of the Solar System. Earth's unique features, including its atmosphere and natural satellite (the Moon), further confirm its status as a celestial body.

No, Earth is not a celestial body because it gets heat and light from the sun. also earth is a non luminous. Not only Earth every planet is not a celestial body.
