How fast does Neptune spin on its axis in mph?
12,146 miles per hour
Neptune: 5.43 km/s (12,146 miles per hour), or a period of about 163.72 years. Pluto: 4.74 km/s (10,603 miles per hour), or a period of about 247.92 years.
What is Neptune’s rotation on its axis?
Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the Sun, which is similar to the axial tilts of Mars and Earth. This means that Neptune experiences seasons just like we do on Earth; however, since its year is so long, each of the four seasons lasts for over 40 years.
What is the size of Neptune in KM?
24,622 km
Neptune/Radius
How fast does each planet spin on its axis?
Earth: 23h 56m, 1574 km/h. Mars: 24h 36m, 866 km/h. Jupiter: 9h 55m, 45,583 km/h. Saturn: 10h 33m, 36,840 km/h.
What is the fastest moving planet?
Mercury
Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Does Neptune spin fast?
But Erich Karkoschka, of the University of Arizona, managed to use these shifting features to calculate how long it takes Neptune to rotate on its axis and complete one day: 15 hours, 57 minutes, and 59 seconds. A video of the Neptune spinning conveys the sheer speed at which the giant planet rotates.
How long is an hour on Neptune?
The Earth is the only planet with an approximately 24-hour day
| Planet | Length of Day |
|---|---|
| Jupiter | 9 hours, 55 minutes |
| Saturn | 10 hours, 33 minutes |
| Uranus | 17 hours, 14 minutes |
| Neptune | 15 hours, 57 minutes |
Is Neptune’s gravity stronger than Earth?
Although Neptune is much larger than Earth, its surface gravity is about the same as the surface gravity on Earth. The surface gravity on Neptune is about 110% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 110 pounds on Neptune (assuming you could find someplace to, well, stand).
How strong is Neptune’s gravity?
11.15 m/s²
Neptune/Gravity
How fast does Neptune spin on its axis?
Neptune takes only 16 hours, 6 minutes and 36 seconds (earth time) to rotate on its axis. This would mean it takes around 2 thirds of an Earth day.
What is Neptune’s rotation rate?
Neptune’s equatorial zone takes about 18 hours to complete a rotation – that’s slower than the planet’s averate 16.1 hour rotation period. And the polar regions can take just 12 hours to rotate; much more quickly than the average.
What is Neptune’s rotation axis?
Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the Sun, which is similar to the axial tilts of Mars and Earth. This means that Neptune experiences seasons just like we do on Earth; however, since its year is so long, each of the four seasons lasts for over 40 years.
What is Neptune’s period of rotation?
Because Neptune is not a solid body, its atmosphere undergoes differential rotation. The wide equatorial zone rotates with a period of about 18 hours, which is slower than the 16.1-hour rotation of the planet’s magnetic field. By contrast, the reverse is true for the polar regions where the rotation period is 12 hours.
