Lunar Eclipse Trivia Questions

It requires a full moon alignment, which happens only at night when the Moon is opposite the Sun in the sky.

Unlike solar eclipses, lunar eclipses are safe to view directly because the Moon only reflects sunlight, not concentrates it.

It turns reddish, not black, due to Rayleigh scattering of sunlight through Earth's atmosphere—called a 'blood moon'.

Earth’s shadow spans about 1.4 million kilometers at the Moon’s distance, so totality can last over an hour.

The Moon must be opposite the Sun and near a node in its tilted orbit. Most full moons miss the Earth's shadow.

Aristotle observed the circular shadow on the Moon during eclipses, providing early evidence for Earth’s spherical shape.

Without sunlight, the lunar surface cools rapidly from about 100°C to -100°C within hours because of no atmosphere.

The maximum is three lunar eclipses in a year, though rarely four can occur. Five is impossible due to orbital mechanics.
