The definition of "planet" set in 2006 by the International Astronomical Union (IAU) states that in the Solar System a planet is a celestial body that: # is in orbit around the Sun, # has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and # has "cleared the neighborhood" around its orbit.
Before classifying a heavenly body as a dwarf planet, considerations include its size (not massive enough to clear its orbit of other debris), its shape (does not have a spherical shape), and its orbit (must orbit the sun and not be a satellite of another planet). These criteria are outlined by the International Astronomical Union for defining dwarf planets.
A heavenly body that orbits a planet is called a moon. Moons can vary in size, shape, and composition, and they play a significant role in stabilizing the rotation of their host planet.
It is referred to as the planet's "axis."
Some do and some don't. Some planets have more then one moon. By definition a heavenly body that circulate another heavenly body is called a moon. A heavenly body that circulates a star (sun) is called a planet.
A natural satellite, or a moon.
Planet.
the following answer originates from my knowledge and is not copyright material . the underlined words were not hyperlinks and have been done so for the public's better understanding.if an heavenly body orbits a star it is called a planet.if the size of the heavenly body is normal(in comparison to that of the inner planets of our solar system) it is just called planetif it is smaller it is called a dwarf planet.if it is bigger it is called a giant planet,gas giant,ice giant,super planet,or basically whatever it is made up of.if the same heavenly body orbits a planet is becomes a satellite
Satellite.
An eclipse takes place when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. There are two types of eclipses on Earth: an eclipse of the moon and an eclipse of the sun.
It is called a satellite. Earth has one of them, other planets many more.
A material, but incorruptible heavenly body could be an asteroid, or a dwarf planet. Material means that it is made of something other than air or gas. Incorruptible means that it is a solid object. Heavenly body means that it is up in the sky or outer space.
A heavenly body that orbits a planet is called a moon. Moons can vary greatly in size and composition, with some being rocky and others icy. Earth’s moon is one of the most well-known examples, but many other planets in our solar system also have multiple moons.
