Celestial Bodies
Natural objects visible in the sky, such as the Sun, Moon, stars, and planets, are called celestial bodies.
The Solar System
Our solar system consists of the Sun at the center and eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) along with their moons, asteroids, and comets orbiting it.
Phases of the Moon
The changing shapes of the bright part of the Moon as seen from Earth over about 29.5 days are called phases of the moon, caused by its revolution around Earth.
Artificial Satellites
Man-made objects launched into space that orbit the Earth, used for communication, weather forecasting, and scientific research.
Constellations
Groups of stars that form recognizable patterns in the night sky, such as the Great Bear (Saptarshi) or Orion.

Frequently Asked Questions
Why do stars twinkle while planets do not?
Stars are very far away and appear as tiny points of light, whose light gets distorted by Earth's moving atmosphere, making them twinkle. Planets are closer, appear as discs, and their light averages out so they do not twinkle.
What is the difference between a natural satellite and an artificial satellite?
A natural satellite is a celestial body that orbits a planet naturally, like the Moon. An artificial satellite is a man-made machine launched into space to orbit Earth for communication and research.
Why do we always see only one side of the Moon?
The Moon takes the same amount of time to complete one rotation on its axis as it does to complete one revolution around the Earth (about 27.3 days).
