Frequently Asked Questions
Why is Pluto no longer considered a planet?
Pluto is classified as a dwarf planet because it is too small and has not cleared its neighboring region of other objects.
What is the difference between a solar eclipse and a lunar eclipse?
In a solar eclipse, the Moon blocks the Sun from Earth. In a lunar eclipse, the Earth blocks sunlight from reaching the Moon.
Why does the Moon change its shape every night?
The Moon does not actually change shape; we see different amounts of its illuminated half from Earth depending on its position in its orbit.
