zero-gravity

Astronauts float here

Zero-gravity describes the condition of apparent weightlessness, as experienced in orbit or free fall.

Objects and people float rather than being pulled to a surface: astronauts training in zero-gravity conditions, a zero-gravity chamber.

Technically, gravity still acts on orbiting bodies—they're falling continuously around Earth—but the effect feels like weightlessness.

Also called zero-G or microgravity.
