Frequently Asked Questions - Stars and Solar System
A star is a celestial object that emits light and heat due to nuclear reactions happening in its core.
Stars are formed from clouds of gas and dust called nebulae. Gravitational collapse and fusion reactions in the core lead to star formation.
The solar system consists of the Sun, eight planets, their moons, asteroids, comets, and other celestial objects bound by gravity.
The Sun is the central and most massive object in the solar system. It provides light, heat, and energy through nuclear fusion.
Planets are classified into terrestrial planets (small, rocky) and gas giants (large, gaseous) based on their characteristics.
A constellation is a group of stars that appear to form a pattern or shape in the sky, often with mythological significance.
The Moon's gravitational pull causes tides on Earth, influencing ocean levels and marine life.
Comets are icy bodies that develop tails when approaching the Sun, while asteroids are rocky objects orbiting the Sun, mostly found in the asteroid belt.
Stars appear different in color due to variations in temperature. Hotter stars are bluish-white, while cooler stars are reddish.
A galaxy is a massive system of stars, planets, gas, and dust held together by gravity. Our Milky Way galaxy is just one of billions in the universe.
