How wide is the world

Answered by GPT-5 mini AI
Do you mean the planet Earth? If so, “width” depends on how you measure it (Earth is an oblate spheroid, a bit flattened at the poles).

Key values (rounded):

- Equatorial diameter: about 12,756 km (≈ 7,926 mi)
- Polar diameter: about 12,714 km (≈ 7,901 mi)
- Mean diameter: about 12,742 km (≈ 7,918 mi)
- Equatorial circumference: about 40,075 km (≈ 24,901 mi)
- Meridian (pole-to-pole) circumference: about 40,008 km (≈ 24,860 mi)
- Surface area: ≈ 510,072,000 km² (≈ 196,940,000 mi²) — land ≈ 148,940,000 km², water ≈ 361,132,000 km²

If you meant something else by “world” (a map projection, the habitable world, or a metaphorical question), tell me which and I’ll give the appropriate answer.
