| Year Length | 365.25 days | 164.79 Earth years |
| Relative Size | 1 | 3.9 times larger |
| Relative Mass | 1 | 17 times more massive |
Weight Comparison
On Neptune, objects weigh approximately 14% more than they do on Earth4. This means that if you weigh 100 kg on Earth, you would weigh about 114 kg on Neptune. Here's a quick comparison of weights for various objects:
| Object | Weight on Earth (kg) | Weight on Neptune (kg) |
|---|---|---|
| Person (70 kg) | 70 | 78.4 |
| Dog (15 kg) | 15 | 16.8 |
| Cat (5 kg) | 5 | 5.6 |
| Elephant (6000 kg) | 6000 | 6720.0 |
| Car (1500 kg) | 1500 | 1680.0 |
Key Facts
- Size Difference: Neptune is 3.9 times larger than Earth in diameter5.
- Mass Comparison: Neptune is 17 times more massive than Earth5.
- Gravity: Despite its larger size, Neptune's surface gravity is only slightly stronger than Earth's due to its gaseous composition4.
- Day Length: A day on Neptune is shorter than on Earth, lasting only 16 hours and 6 minutes5.
- Year Length: A year on Neptune is much longer, equivalent to 164.79 Earth years5.
- Composition: Neptune is an ice giant, composed primarily of gases and ices, unlike Earth's rocky composition1.
To calculate your weight on Neptune, you can multiply your Earth weight by 1.14 or use the formula:Weight on Neptune = (Weight on Earth / 9.81 m/s²) × 11.15 m/s²2This comparison highlights the fascinating differences between Earth and Neptune, showcasing how diverse planetary conditions can be within our solar system.
