How do dwarf planets form?

Answer 1

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.

Answer 2

There are many different types of planets in the galaxy. Dwarf planets were formed from left over space debris created by the formation of the rest of the planets.

Answer 3

they were formed just like earth and the moon

Answer 4

A white dwarf can be formed by a small star and it's electron degeneracy pressure simply stops.

While a black dwarf is formed by a white dwarf using up all it's energy

Answer 5

because scientists thought it was to small to be a planet or it shape cannot be a shpere.

Answer 6

When two planets meet they make babys
