Frequently Asked Questions
Why do stars twinkle at night?
Stars twinkle because their light passes through Earth's moving layers of atmosphere, which bends the light in different directions before it reaches our eyes.
Is the Sun a star or a planet?
The Sun is a star because it has its own heat and light, unlike planets which reflect light from the Sun.
What is the difference between a natural satellite and an artificial satellite?
Natural satellites like the Moon are created by nature and orbit planets, while artificial satellites are man-made devices sent into space for communication and weather tracking.
