celestial Overview
Our solar system, a captivating cosmic realm, is a harmonious ballet of celestial bodies orbiting a central star, the Sun. Surrounding the Sun is a family of planets, traditionally divided into two categories based on their composition: terrestrial and gas giants.This intricate system, composed of planets, moons, asteroids, comets, and dwarf planets, has fascinated humanity for millennia, inspiring countless myths, legends, and scientific inquiries. At the heart of our solar system lies the Sun, a magnificent sphere of incandescent gas primarily composed of hydrogen and helium. Its immense gravitational pull holds the entire system together, providing the energy that sustains life on Earth. The Sun's core, where nuclear fusion occurs, generates tremendous heat and light, which radiates outwards, warming the planets and making life possible.

Surrounding the Sun is a family of planets, traditionally divided into two categories based on their composition: terrestrial and gas giants.
The Terrestrial Planets
The inner, rocky planets, often referred to as terrestrial planets, are characterized by their solid, dense composition. They include Mercury, Venus, Earth, and Mars.


• Mercury, the closest planet to the Sun, is a small, cratered world with extreme temperature variations. Its proximity to the Sun makes it incredibly hot during the day and frigid at night.


• Venus, often called Earth's "twin" due to its similar size and density, is shrouded in a thick atmosphere of carbon dioxide, creating a scorching greenhouse effect. It's the hottest planet in the solar system.

• Earth, our home planet, is a unique oasis of life, with liquid water, a complex atmosphere, and a diverse range of ecosystems. Its large moon, Luna, plays a crucial role in stabilizing Earth's rotation and creating tides.




• Mars, the "Red Planet," is a cold, desert world with a thin atmosphere. Its surface is marked by vast canyons, volcanoes, and evidence of ancient water flow, raising intriguing questions about its past

7. Eclipse : Solar eclipse Lunar eclipse

8. ECLIPSE Eclipse : An eclipse  occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body . Solar Eclipse : A solar eclipse occurs when the Moon passes between the Sun and the Earth . The Moon casts a shadow onto the surface of Earth. This image shows a partial or annular solar eclipse where the Sun is only partially obscured by the Moon. Lunar Eclipse : Also known as the eclipse of the moon,  it occurs when the earth comes in between the sun and the moon . As a result, the earth blocks the light of the sun from reaching the moon's surface and casts its shadow on the moon. It occurs on a full moon day. We can observe up to 3 lunar eclipses per year.

10. Solar Eclipse : A solar eclipse occurs when the Moon passes between the Sun and the Earth. The Moon casts a shadow onto the surface of Earth. This image shows a partial or annular solar eclipse where the Sun is only partially obscured by the Moon .

11. Lunar Eclipse : Also known as the eclipse of the moon, it occurs when the earth comes in between the sun and the moon. As a result, the earth blocks the light of the sun from reaching the moon's surface and casts its shadow on the moon. It occurs on a full moon day. We can observe up to 3 lunar eclipses per year.

12. planet Terrestrial Planets These planets are primarily composed of rock and metal. Mercury: Closest planet to the Sun. No atmosphere. Extreme temperature variations. Craters similar to the Moon .

13. VENUS Venus: Often called Earth's "twin" due to similar size and density. Thick atmosphere of carbon dioxide. Hottest planet in the Solar System. Rotates in the opposite direction of most planets.

14. Earth: Only planet known to support life. Liquid water, oxygen-rich atmosphere. Active geological processes. One moon.

15. MARS Mars: Often referred to as the "Red Planet" due to iron oxide on its surface. Thin atmosphere, primarily carbon dioxide. Evidence of water in the past. Two small moons (Phobos and Deimos).
