Mainly through gravity - the bodies attract one another. This means that gradually, over a long period of time, the gravitation of one planet can change the orbit of another planet.
all parts of the planet pulled each other toward the center of the mass by gravity
Prions affect the nervous system (the brain and other neural tissue).
The planets or other cosmic objects are very different, not similar.
By definition, the planet Earths average distance is 1 AU (astronomical Unit) from the sun. This is about 93 million miles or 150 million km.

Asteroids and Comets.
Cosmic dust and other astronomical bodies.
The oldest astronomical bodies are likely the stars in the universe, which formed around 13.8 billion years ago. Next are galaxies, which began forming shortly after the Big Bang. Planets, moons, asteroids, and other smaller bodies in our Solar System are relatively younger, with Earth estimated to be around 4.5 billion years old.
An armillary sphere is a device for studying the rotation of the earth and other astronomical bodies (i think lol)
Study of celestial bodies or astronomical objectsadditional and attempting to predict the future or other outcomes from this data. Not concepts supported by science.

It was not one scientist that made this decision but the International Astronomical Union (IAU), which is the body officially recognized by astronomers and other scientists worldwide as the naming authority for astronomical bodies.
Earth. An Astronomical Unit is a unit of distance measure defined as the mean (average) distance between the Earth and the Sun; thus, the earth orbits the sun at a distance of 1 Astronomical Unit. The Astronomical Unit was invented to make it easier to think of astronomical distances within the Solar System ... it is easier to get a feel for how close the planets and other bodies in the solar system are close to the sun in terms of Astronomical Units (AUs) than millions of kilometers: Mercury at 0.4 AU versus 50 million kilometers, Venus at 0.7 AU versus 108 million kilometers, etc.

Astronomy
The solar system is the collection of all the planets that revolve around the sun and other smaller bodies. These other bodies include the moon, comets, meteoroids and asteroids among others.
