Celestial Bodies
Natural objects visible in the sky, such as the sun, moon, stars, and planets, are called celestial bodies.
The Solar System
The sun, eight planets, their moons, and other celestial bodies like asteroids and meteors form the solar system, with the sun at the center.
Stars and Constellations
Stars are giant celestial bodies made of hot gases that emit their own light, while constellations are recognizable patterns formed by groups of stars in the night sky.
Natural and Artificial Satellites
A natural satellite is a space body that orbits a planet, like the moon orbits Earth, whereas artificial satellites are human-made objects launched into space for communication and weather forecasting.
Asteroids and Meteoroids
Asteroids are rocky chunks revolving around the sun mostly between Mars and Jupiter, and meteoroids are smaller pieces of rocks that burn up upon entering Earth's atmosphere.

Frequently Asked Questions
Why do stars twinkle while planets do not?
Stars twinkle because they are very far away and appear as tiny points of light whose beams get bent by Earth's atmosphere. Planets are closer, appear as disks, and their light averages out, preventing twinkling.
What is the difference between a star and a planet?
Stars have their own heat and light, whereas planets do not produce their own light and instead reflect the light of the sun.
Why is Pluto no longer considered a planet?
Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because it does not clear its neighboring region of other objects.
