Feel every
world's pull.
Enter your mass and pick a world. We'll show what you'd weigh, how high you'd jump, how long a fall would take, and how fast you'd need to fly for a stable low orbit.

Same take-off velocity, two different worlds. Press launch to see how high — and how long — the same jump would carry you.

Jump height assumes a constant take-off velocity equal to an average 0.5 m Earth vertical jump. Flight time scales with √(peak/g) — low-gravity worlds keep you airborne much longer.
