How big is Jupiter?
Short answer: About 142,984 km in diameter (88,846 miles) (71,492 km radius).
Long answer: Because Jupiter is a gas giant planet that rotates quickly (once every 9.8 hours), it bulges out a bit at the equator. That's why the equatorial radius is larger than the polar radius.
- Equatorial radius: 71, 492 km (44,423 miles) (11.2 × Earth)
- Polar radius: 66,854 km (41,541 miles) (10.5 × Earth)
- Surface area: 6.1419 × 1010 km2 (2.3714 ×1010 miles2) (121.9 × Earth)
- Volume: 1.4313 × 1015 metres3 (3.43 × 1014 miles3) (1,321 × Earth)
- Mass: 1.8982 × 1027 kg (4.18 × 1027 pounds) (317.8 × Earth)
