Based on the principles of physics, it is theoretically possible for a planet to have a donut-shaped structure. To maintain the stability of a donut-shaped Earth, it would need to rotate at extremely high speeds, resulting in shorter day durations. Consequently, the gravitational force at the poles would intensify, approximately twice as strong as at the equator. The Moon would continue to orbit the Earth, as long as it maintains a sufficient distance. If the donut-shaped Earth has no tilt, the inner edges would receive no sunlight, while the outer edges would experience increased sunlight exposure, leading to significant temperature variations and extreme weather conditions. However, if the tilt remains unchanged, both the inner and outer edges would receive adequate sunlight. It is worth noting that a naturally occurring donut-shaped planet is highly unlikely unless advanced extraterrestrial beings decide to create one.
