An eclipse occurs when one celestial body blocks light from reaching another. There are two main types: solar eclipses, where the Moon blocks the Sun, and lunar eclipses, where the Earth blocks sunlight to the Moon.
Scientists measure distances between celestial bodies using various methods, including astronomical units, light-years, and parsecs. Techniques like radar ranging, parallax measurements, and observations of star positions help determine these distances.
Earth is suitable for life due to its optimal distance from the Sun, presence of water, breathable atmosphere, and suitable temperatures. These factors create a habitable environment for diverse forms of life.
The solar system is a collection of celestial bodies, including the Sun, planets, moons, asteroids, and comets, that orbit around the Sun due to its gravitational pull.
Visiting a planetarium or science museum is a great opportunity. At night, you can observe the Moon, planets, and stars through telescopes. During the day, enjoy models, pictures, and sky shows to explore the wonders of the universe.
The Solar System includes the Sun, eight planets, their moons, dwarf planets, asteroids, and comets. It is structured with the Sun at the center and planets orbiting it in elliptical paths.
Venus is called Earth’s twin due to its similar size, mass, and composition. However, its thick atmosphere creates extreme greenhouse conditions, making its surface temperature much higher than Earth’s.
