I scientifically believe that comets are closer to the outer part of the solar system.
No. They form in the outer solar system where it is cold enough.
Comets originate from the Oort cloud, a spherical shell of icy bodies at the outer edges of our solar system. These comets can be perturbed and sent into the inner solar system where they become visible as they approach the Sun.
inner
Jupiter is not one of the inner planets. The solar system has four inner planets, which starting with the one that is closest to the sun are Mercury, Venus, Earth, and Mars, followed by the asteroid belt (which is a division between the inner and outer system) and then the four outer planets, which are Jupiter, Saturn, Uranus, and Neptune. After that are various dwarf planets, and the comets.
In the outer realms of the solar system.
Inner or outer, relative to what? - There is only one Sun in our Solar System. It is basically in the center of the Solar System.
They are more similar to the inner planets, since they are rocky and icy in nature instead of gaseous.
They are from extreme outer parts of the solar system (known as "Kuiper belt") and from a huge cloud of comets lying far beyond the orbit of Pluto, completely surrounding the Sun (known as "Oort cloud").
Earth is part of the Inner Solar System.
Comets. The Oort Cloud is a vast region of space beyond the orbits of Pluto and the other outer planets where many comets are believed to originate. These icy objects can be pushed into the inner solar system by gravitational forces and become visible as comets when they approach the Sun.
Most "asteroids" are in orbit around the Sun, unless disturbed by gravity or collisions. Comets may orbit the Sun regularly, or be drawn in from the outer solar system and pass by the Sun on their way back out (hyperbolic comets).
No. Mercury is the closest thing to the Sun, and comets are normally around the outer areas of the solar system.
