If our round Earth has a surface gravity of 1 G, the surface gravity of a donut Earth along the poles would be 0.65 G. And at the equator, the gravity would go down to just 0.3 G. It would be like walking on the surface of ________.
Mars
To fight the urge to become a sphere-shaped Earth, a donut Earth would have to spin much faster than our round Earth does. That way, centrifugal forces would kick in and keep the donut hole intact. But because of this quick rotation, a day on Earth would only last 2 hours and 50 minutes. Or, if you prefer to stick to a traditional 24-hour day, you’d be dealing with at least eight sunrises and sunsets every day. You’d have to adapt to working day and night, and sleeping through hours of ________.
daylight
But the weather would be a little more extreme. It’s hard to predict where the countries would be located on a torus planet. But as far as topography goes, most likely, the donut hole would be lined with ________.
mountains
But at least there would be no mass extinction, and no areas of the planet would become too extreme for us to survive. Donut-Earthers might, or might not, have the tools and tech we have today. They might not even stumble onto the concept of a donut in the first place. Or, they could be making videos like “What if the Earth was shaped like a ball?” And maybe because of this donut shape, some disasters in Earth history would never happen, but that’s a story for another ________.

At the donut’s equator, the escape velocity would go down to just 6.5 km/s. So if you were to send rockets into space, that would be the best place to break free of the gravitational clutches of a donut-shaped Earth. Speaking of gravity, depending on where you were on a torus Earth, you’d weigh up to three times less than you usually do. If our round Earth has a surface gravity of 1 G, the surface gravity of a donut Earth along the poles would be 0.65 G. And at the equator, the gravity would go down to just 0.3 G. It would be like walking on the surface of ________.
