Is a day on Venus longer than a year on Venus?

Yes. Venus takes about 243 Earth days to spin once on its axis, but only about 225 Earth days to travel all the way around the Sun. A Venusian day is longer than a Venusian year.

Would Saturn float in water?

On average, yes. Saturn's mean density is about 0.69 grams per cubic centimetre, lower than water's 1.0, making it the only planet in the solar system less dense than water. Given a big enough bathtub, it would float.

Is the Moon moving away from Earth?

Yes. The Moon drifts about 3.8 centimetres further from Earth every year — roughly the rate your fingernails grow. It is a direct measurement, not a model, taken by bouncing lasers off reflectors the Apollo astronauts left behind.

Are there more trees on Earth than stars in the Milky Way?

Yes, by a wide margin. A 2015 study in Nature put the global tree count at roughly 3.04 trillion. The Milky Way is generally estimated to hold somewhere between 100 and 400 billion stars — around ten times fewer.

Are there more possible chess games than atoms in the universe?

Yes. The number of possible chess games is estimated at around 10^120, known as the Shannon number. The observable universe contains roughly 10^80 atoms. Chess outruns it by about forty orders of magnitude.

Do octopuses really have three hearts?

Yes. An octopus has three hearts: two branchial hearts that push blood through the gills, and one systemic heart that sends it around the body. The systemic heart stops beating when the octopus swims, which is part of why they would rather walk.

Why is wombat poop cube-shaped?

Because their intestines are not uniformly stiff. Research published in Soft Matter found regions of the wombat's gut are twice as thick and four times as stiff as neighbouring regions, so contractions mould corners into the faeces over the final stretch of intestine.

Are sharks older than trees?

Yes. Sharks appear in the fossil record around 450 million years ago; the first true trees show up around 385 million years ago. Sharks predate forests by roughly 65 million years — about the same gap that separates us from the last dinosaurs.

How hard does a mantis shrimp punch?

Fast enough to boil water. A 2004 Nature study clocked the peacock mantis shrimp's club at around 23 metres per second, accelerating like a bullet. The strike drops the water pressure so sharply that vapour bubbles form and violently collapse — so prey gets hit twice.

Can turtles really breathe through their butts?

Some can. Several freshwater turtles absorb oxygen through the lining of the cloaca. The Fitzroy River turtle of Australia does it well enough to meet effectively all of its oxygen needs this way, letting it stay submerged for extraordinarily long stretches.

Do sea otters hold hands while they sleep?

Sometimes, genuinely. Resting sea otters do link paws so they don't drift apart from their raft. It is real behaviour and not a myth — but it is less frequent than the internet implies, and rafts mostly stay together by watching and listening to each other.

Can bees recognise human faces?

Yes. In a 2005 study, honeybees were trained on photographs from a standard human face-recognition test and picked the target face out from a similar distractor with better than 80 percent accuracy — and still remembered it two days later.

Each one starts with something familiar, then turns it sideways. Every claim links to a source you can open and check.

Cleopatra lived closer to the Moon landing than to the pyramids

Honey does not spoil, and we have 3,000-year-old proof

Sealed honey never spoils — 3,000-year-old Egyptian honey is still edible.

Today’s truth

That cloud weighs about a million pounds

An average cumulus cloud holds roughly 500,000 kilograms of water — about 1.1 million pounds, or 550 tons. It floats because the air underneath it is denser than the cloud is, not because the cloud is light.

Why you can trust this

The internet is full of facts that are almost true. Odd Truths is the small, stubborn opposite of that.

Everything is cited

Every truth links to at least one primary or reputable source. No source, no entry. That rule is the entire editorial policy.

Nuance stays in

Where the popular version overstates things, we say so. A fact that needs a caveat gets its caveat rather than a better headline.

Corrections welcome

If something here is wrong, it gets fixed rather than quietly deleted. Following the evidence is the point.
