The Moon's orbit doesn't spiral around Earth as most people imagine. Because the Earth-Moon distance is tiny compared to the Earth-Sun distance, the Moon's actual path through space is nearly circular, traveling alongside Earth around the Sun.

Earth's closest planet on average isn't Venus but Mercury. Bigger orbits spend longer on the far side of the Sun, so average distance grows. Mercury's tiny orbit keeps it near every planet. Earth–Mercury averages 1.04 AU, Earth–Venus 1.14 AU. The "Whirly Dirly Corollary."

Cleopatra lived closer in time to the Moon landing than to the construction of the Great Pyramid of Giza. The pyramid was finished around 2560 BC, Cleopatra was born in 69 BC, and Apollo 11 landed in 1969 AD. To her, the pyramids were already a 2,500-year-old relic.

There are more trees on Earth than stars in the Milky Way. A 2015 Nature study estimated about 3 trillion trees, while NASA counts 100 to 400 billion stars—over seven times more trees. The same study found Earth's trees have dropped about 46% since civilization began.
