According to the laws of physics, a planet in the shape of a doughnut (toroid) could exist Physicists say that such a planet would have very short nights and days, and arid outer equator, twilight polar regions, moons in strange orbits and regions with different gravity and seasons.
Actually, I’m reblogging this again. Because I just wanted to say this is a brilliant thing to potentially add to a story at some point and I want to tag this so I can find it later.
Earth is a donut, confirmed

“Though my soul may set in darkness, it will rise in perfect light;
I have loved the stars too fondly to be fearful of the night.”A little doodle for one the most beautiful lines from any poem, The Old Astronomer. Available on S6 for those who asked 🙂
good one Neil we’re gonna start an interplanetary war after the aliens discover we named their planet Dopey
This is very cool and a pretty big deal. Find out why.
The solar system is all set to give a rare celestial show. Mercury, Venus, Saturn, Mars and Jupiter will all be visible from Earth when they appear in a diagonal line on Wednesday, Jan. 20. It’s the first time the five bright planets, so called as they can usually be seen easily with the naked eye, have aligned in such a way in more than 10 years. The phenomenon will continue until Feb. 20.

The astronomer whose work helped kick Pluto out of the pantheon of planets says he has good reason to believe there’s an undiscovered planet bigger than Earth lurking in the distant reaches of our solar system.
That’s quite a claim, because Mike Brown of Caltech is no stranger to this part of our cosmic neighborhood. After all, he discovered Eris, an icy world more massive than Pluto that proved our old friend wasn’t special enough to be considered a full-fledged planet. He also introduced the world to Sedna, a first-of-its-kind dwarf planet that’s so far out there, its region of space was long thought to be an empty no man’s land.
Now Brown has teamed up with Caltech colleague Konstantin Batygin to do a new analysis of oddities in the orbits of small, icy bodies out beyond Neptune. In their report published Wednesday in The Astronomical Journal, the researchers say it looks like the orbits are all being affected by the presence of an unseen planet that’s about 10 times more massive than Earth (though still much smaller than Uranus or Neptune) — the size astronomers refer to as a super-Earth.
