Take a look at this thing! 👀 It's a plasma toroid — it starts with a glass globe evacuated and filled with xenon. A coil is placed around the globe with a high-frequency current (10 million cycles per second). The current excites a plasma inside the globe, but due to the coil's magnetic field, the plasma is confined to a toroidal (doughnut-like 🍩) space, forming a plasma toroid. The plasma circulates inside the globe indefinitely. ⚡ To see even more cool high-voltage gadgets, join Harvard Univ

Based on the Laws of Physics, toroidal planet (donut-shaped) is physically possible. But, it would require extreme and very specific conditions to form and remain stable. While most planets form into spheres due to gravitational equilibrium, a toroidal shape would need to fight that natural pull, with extreme rotation or external forces. Such a shape could arise from a rapidly spinning disk of material, where centrifugal forces keep the center from collapsing. Think of it like stretching a spher

Donut-shaped planets, or toroidal planets, could theoretically exist under specific conditions where the forces shaping the planet allow for such an unusual geometry. These planets would require an extremely rapid rotation during their formation, generating immense centrifugal force that counteracts gravitational collapse into a sphere. Additionally, their internal structure would need to be highly stable, possibly with a dense core or unique material distribution to maintain the toroidal shape.
