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.
What is the difference between a star and a planet?
Stars have their own heat and light, whereas planets do not produce their own light and only reflect the light of the Sun.
Why is Pluto no longer considered a planet?
Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because it shares its orbital zone with other large objects.
