How many Earth years does it take for one Neptune orbit?
165 years
What is Neptune's main moon?
Triton
Who is Neptune named after?
The Roman God of Sea
Can you stand on Neptune?
No.
How long is a day on Neptune?
16 hours.
What was the only NASA spacecraft to fly by Neptune?
Voyager 2
This gas in Neptune's atmosphere absorbs red light, giving the planet its vibrant blue color.
Methane
Neptune has the fastest winds in the solar system, reaching speeds of over this many miles per hour.
1,200 (but I'll accept 1,000)
While they are very faint and dark, Neptune has at least five of these circular features surrounding it.
Rings
This is the total number of known moons orbiting Neptune.
14
Neptune is categorized as this type of "giant," a term shared only with Uranus.
Ice Giant
Neptune’s largest moon, Triton, is unique because it orbits the planet in this "backward" direction.
Retrograde.
To find Neptune, astronomers noticed a "gravitational tug" on this next-door neighbor planet.
Uranus
Because it is so far from the Sun, Neptune is the coldest or this number planet in our solar system.
The eighth planet.
Voyager 2 discovered this fast-moving white cloud, named after a small motorized vehicle.
the Scooter
Deep inside Neptune, high pressure is thought to turn carbon into this precious gemstone that "rains" toward the core.
Diamonds
Neptune is the only planet in the solar system discovered using mathematics before it was ever seen with this.
A telescope
This Earth-sized storm was first seen by Voyager 2 in 1989 but had completely vanished by 1994.
Great Dark Spot
One of Neptune's five rings contains "arcs" with names like Liberté and Fraternité, which are words from this language.
French
Because it is so far from the Sun, Neptune has only completed this many full orbits since its discovery in 1846.
One
Even though it is the farthest planet from the Sun, Neptune actually generates more of this type of energy internally than it receives from the Sun.
Heat
Neptune is roughly this many times wider than Earth.
Four
Because of its blue color, Neptune's moons are named after minor gods of this, like Triton and Proteus.
Water. (or the sea)
Because Neptune is so big but made of gas and ice, its gravity is surprisingly almost the same as this planet’s.
What is Earth
In 2022, this famous new space telescope took the clearest picture of Neptune’s rings in over 30 years.
