• Must have at least 1 or more moons.
• Must have a diameter greater than 1,500 km
• Must have a mass of at least 0.002 of Earths mass
• Must have at least a gravity of 0.05 of Earths mass
• Must have an orbital period less then 400.0 Earth
years
• Mean distance from the sun has to be more then .70
but less than 40.0 AU

Why are these considered dwarf planets instead of regular planets?
Mercury is not a planet because it has no moons and the mean distance from the
sun is .39 when it should be greater then .70.
Venus is not a planet because it does not have any moons.
Ceres is not a planet because of a few reasons. It has no moons, It mass is less
then 0.002, it is 0.00016. Its gravity of earths mass is not greater then 0.05. It is
0.028.
Haumea is not a planet because the mass is not greater then 0.002, it is .00070.
The gravity of the earths mass has to be 0.05 of earths mass, Haumea isn’t, its
gravity is 0.045. The last reason it isn’t a planet is because the mean distance
from the sun has to be less then 40.0, Haumea is 43.34.
Why are these considered dwarf planets instead of regular
planets?
Makemake is not a planet because it has no moons, the mass
isn’t greater then 0.002, it is 0.00067 of earths mass. The last
reason is because the mean distance from the sun has to be
less then 40.0, It is 45.79.
Eris is not a planet because its orbital period is not less then
400.0 of earths years, it is 557.00. The other reason it is not a
planet is because the mean distance from the sun is greater
then 40.0, it is 67.67 AU.
