What are called planetoids or minor planets?
Asteroids are rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, ranging in size from hundreds of miles to several feet across. In total, the mass of all the asteroids is less than that of Earth’s moon.
Why are meteoroids not considered dwarf planets?

Is Earth a minor planet?
That means that according to the definition of the International Astronomical Union, the Earth cannot technically be considered as a planet and that it is, in fact, a dwarf-planet. There were seven earth sized objects discovered in orbit around an ultracool dwarf star forty light years away using this method.

Is Earth a dwarf?
It turns out that Earth is not a planet. Therefore, under the definition of a planet vigorously defended by the IAU since the adoption of Resolution 5A on August 24, 2006, Earth is a ‘dwarf planet’ because it has not cleared its orbit, which is the only one of the criteria of their definition that Pluto fails.
