Some have a very thin atmosphere layer, some do not have any atmosphere at all.
The name of the third dwarf planet is spelled "Makemake."
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star that is massive enough to be spherical as a result of its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite.
Ceres, discovered Jan. 1, 1801 by Piazzi. He and other astronomers were looking for the "missing" planet that "ought" to exist between the orbits of Mars and Jupiter. Ceres is about 900 km in diameter.
If you compare it to Earth and Earth is 1 for mass, Pluto is 0.002.
1.3057×1022 kg

The seven dwarfs are:
Bashful
Doc
Dopey
Grumpy
Happy
Sleepy
Sneezy
Anyone else is not one of the seven dwarfs.
Planet
No. Jupiter is not a dwarf planet. Pluto, Ceres, Eris, Makemake, Hauma are dwarf planets.
No. Pluto is a dwarf planet, not a star, and is not visible to the naked eye.
Pluto is way to small to be a planet.Now we have 8 planets in our solar system not 9.Pluto is much smaller then earths moon!If Pluto was just a little bit smaller then Mercury, it would be a planet, but Pluto is TINY compared to mercury.
Earth has water, oxygen, and life on it. Mercury is rocky very hot dead planet with no atmosphere. Venus is a dead planet covered with extremely hot poisonous gas with a very thick atmosphere that crushes anything on the surface.
Of what? Mammals? Animals? In terms of absolute size, or relative to their mass? Pose a more accurate question please. However, fun fact: Neanderthal's brains were both heavier and larger, proportional to their body size, than modern humans brains. Bigger isn't always better.
As of January, 2009, there are 5 dwarf planets, and only the asteroid Ceres is close enough to the Sun (just past Mars) to get appreciable solar heating. Surrounded by the vacuum of space, the "hottest" its surface gets is about -34°C.
No. The only planet available to support life is planet earth. Pluto is on average at least -50 degrees.
They are categorized as "dwarf planets" now, leaving only 8 regular planets in our solar system. The names of all the dwarf planets are:
Ceres
Pluto
Haumea
Makemake
Eris
Dwarf planets are smaller than regular planets.
Dwarf planets are smaller than the 8 major planets of our solar system. They are not quite planets as they have not cleared their orbit of sufficient matter. They are roughly spherical in shape and orbit the sun directly, so fulfil these two criteria, but have not achieved the third (sufficiently clearing their orbits).

Dwarfism can be diagnosed by X-rays to show a short stature at a later time in pregnancy. Dwarfism's scientific name is Achondroplasia. Another symptom is the box feet on an infant. The prevalence rate in Dwarfism in about 1 in every 40,000 new born infants every year.
Ceres is not considered a planet, since it does not dominate its orbit. There are other sizable objects at that distance from the sun, in orbit around the sun. It is a dwarf planet though.
The International Astronomical Union (IAU) recognises eight planets in our solar system (from closest to sun to furthest);
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
A further five dwarf planets are recognised by the IAU;
Ceres (in the asteroid belt between Mars and Jupiter), Pluto, Haumea, Makemake and Eris.
A dwarf planet is not considered a planet because it does not dominate its orbital path and cannot clear that path of debris.
Here are some facts about Pluto:
