Dwarf Planet Haumea
Tucked away in the Kuiper Belt, Haumea is a dwarf planet named after the Hawaiian goddess of childbirth. It was discovered in 2004 and recognized as a dwarf planet in 2008.

How long does it take to get to Haumea?
With our current spacecraft technology, getting a small probe out to the Kuiper Belt to visit a dwarf planet such as Haumea would take at least ten years. As technology improves spacecraft will get faster and more efficient, decreasing travel time, but until then it would take quite a long time.
How big is Haumea the dwarf planet?
Haumea, the dwarf planet, unlike the other 8 planets that we're used to, is
nowhere near spherical. So it has many different circumferences, depending on
where and how you take the 'cross-section'.
The on-line reference that I found describes Haumea's shape as something like
a large potato, and lists its dimensions as
1,960 × 1,520 × 1,000 km (1,220 × 940 × 620 miles).
If we were to assume that the cross-section along the largest dimension is circular,
then the circumference of that section would be 1,220 x pi = 3,833 miles.
Comment: There's something strange about that answer. A dwarf planet by definition has to be roughly spherical. I think Haumea is a "prolate spheroid". That's a shape like an American football, or a rugby ball. Its average radius is very roughly 600 km. (I must say the drawings of Haumea don't look very spherical to me.)
So, its circumference must be very roughly 3800 km. That's a coincidence. I get almost the same answer, but in kilometers not miles!
Is there any water or volcanos on Haumea?
There is a lot of water on Haumea, though due to its cold temperatures, all of it (at least on the surface) is frozen. We do not know enough about its surface to definitively say if it has volcanoes, though other pieces of evidence suggest it might.
Can you see Haumea at night without a telescope?
No. It is far too small and too far away to be seen with the naked eye. Even with the most advanced telescopes it wasn't discovered until 2004.
What is the gravitational pull on Haumea?
Haumea has a gravitational pull of 0.63m/s2, or between one fifteenth and one sixteenth that of Earth.
Does Haumea have a stronger or weaker gravity than earth?
It has a much weaker gravitational pull than Earth. Earth's pull is about 9.81 m/s^2 at sea level, while Haumea's is about 0.63m/s^2, or roughly one fifteenth of that on Earth.
How long are days and years on Haumea?
A day on Haumea is just 3.9155 hours. A year is equal to 284.12 Earth-years.
Where is haumea located in the solar system?
Haumea is one of the newly-discovered Kuiper Belt Objects out beyond the orbit of Neptune. It has a perihelion distance of about 35 AU.
How big is earth compared to dwarf planet Haumea?
In terms of mass, Earth is about 1400 times as massive as Haumea. In terms of volume, Earth is about 722.14 times bigger.
What is the wind speed on the planet Haumea?
As far as we know, Haumea does not have an atmosphere, so the wind speed would effectively be zero.
How haumea looks give pictures?
Haumea is a dwarf planet located in the Kuiper Belt, known for its elongated shape and rapid rotation, which gives it an oval appearance. It has a surface covered in crystalline ice and is believed to have a reddish-brown hue due to the presence of various ices and possibly organic compounds. Additionally, Haumea has at least two known moons, and its unique shape and characteristics make it distinct among celestial bodies. For images, you can find pictures of Haumea through astronomical databases or space agency websites.
