The exact rotational period of Makemake, a dwarf planet in our solar system, is not yet known. However, based on the current available data, it is estimated to have a rotational period of around 22.5 hours, give or take a few hours.
Makemake is the third largest dwarf planet and can be found in the Kuiper belt. [See Link]
Neptune's year, or the time it takes to orbit around the sun, is a little under 165 of our Earth years.
I remember waking up freezing one February morning and hearing that the temperature had gone down to 4.3 degrees C (about 39 degrees F)! That is highly unusual though, as the temperature seldom dips below 10 degrees C (50 degrees F) and even then, it's just for a few days.
It's not known for certain but it is believed to be around 2g/cm3, probably inferred from Pluto which is about the same. The Earth for comparison is 5.5153 g/cm3
Zero degrees Kelvin, (approximately minus 273 degrees Celsius) which is considered the temperature at which molecules stop moving entirely. Although scientists attempt to replicate this setting in a controlled laboratory setting, it has yet to occur in such a manner.
No spacecrafts have currently landed or orbited Makemake. The dwarf planet is too far from the Sun (7,800,000,000 kilometers), it would be in the next century when we can send spacecrafts there.
The International Astronomical Union (IAU) is the governing body that approves a name. But Mike Brown is the is the lead Astronomer of the California Institute of Technology and, as discoverer, he has the right to suggest a name.
For the purpose of the equation, ♫ is pi.
T^2=((4♫^2)(R^3))/(G)(Planetary Mass)
T^2 stands for the period, R is the radius of the orbit in metres.
G is the force of gravity, (6.67 X 10^-11), and the Planetary Mass is the mass of the object that is being orbited in kilograms.
The dwarf planet Makemake has at least one moon, tentatively designated S/2015(136742)-1, or MK-2.
It was photographed in April 2015 and announced on April 26, 2016. Its very dark surface and orbital alignment make it very difficult to spot.
Not presently. Occultation observations in 2011 showed no appreciable atmosphere.
The exterior temperature is well below the freezing points of all major gases, so they would be frozen solid. The only way it would be possible is by molecular sublimation, as is thought to give Pluto a very thin transient atmosphere when it approaches perihelion.
Zero-K is. I could have told you that right away, even without seeing the
others, because zero-K is Absolute Zero, and there's no such thing as a
lower temperature. So there might be something else on the list that's
tied for lowest, but there can't be anything that's lower.
In terms of mass, it is about one-third that of Pluto. Its radius is only about 20 km less than that of Pluto, making them very similar in size, though Haumea is very different in shape. Pluto is much more spherical, while Haumea is more oblong.

It is thought that there isn't any water on Makemake because the reasons below:
1. It is highly possible that Makemake only has methane and nitrogen on it.
2. Makemake's average temperature is thought to be −243.2 °C, to cold to support any liquid water. However there is a possibility of ice on Makemake.
To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. A dwarf planet, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets. The last requirement is often deemed silly as many observers have pointed out Neptune hasn't cleared it's orbit of many objects like Pluto making it only fulfilling qualifications as a dwarf planet (a silly classification and the AIU agrees as it is still considered a planet). Some astronomers seek a more static classification of a "Dwarf Planet" (the classification isn't bad but the last requirement they don't fill fails as a defining force) as we will see many exo-planets are likely to test this definition.
A light-year is not a measure of time, but of distance: 5.87 x 1012 miles. The distance light could travel in one year. ______________________________________________________________________ one revolution of planet earth: one year.
the question this should be is: how long is a light year- that answer i do not know A light year is a unit of distance equal to 5,865,696,000,000 miles
There are millions, possibly billions, of planets in the Milky Way. An exact number will never be known.
Makemake is the name that received a dwarf planet of our solar system that was discovered on March 31 of the year 2005 by a team lead by the American Astronomy professor Michael E. Brown. It was named after the creator God of the Rapanui mythology, Rapanui are the native people of the Easter Island.
Every gas has a different liquidation temperature based on what element it is. Hydrogen has a liquidation point of 423.17 degrees below zero F. Or 20.28 degrees K. That is 20 degrees above absolute zero.
