Comets are often not visible until they approach the Sun in the inner solar system, where the heat causes their ices to sublimate and release gas and dust, forming a glowing coma and sometimes a tail. Most comets spend the majority of their time in the cold outer regions of the solar system, making them difficult to detect until they come closer to the Sun. Therefore, while they may be present in the solar system, they are typically only seen when they become active and bright enough to be observed.
Comets are made up of remnants from the early solar system, so their age is generally around the same as our solar system, approximately 4.6 billion years old. While some comets may contain even older material from beyond our solar system, as a whole, comets are not older than our solar system.
Nobody let them in. They formed with the solar system.
Comets can be formed anywhere in space. They are mainly composed of ice and dust, which can be acquired from anywhere in space i.e pieces of chipped planets or random space particle. Hope this was helpful x]

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").
Occasionally they enter the realm of the inner solar system and become visible .five kilometers is a typical size -- but some are much larger.
Yes. The solar system is everything that orbits the sun.
All the comets that have been seen in history were in the solar system and most still are.

All visible comets go through the solar system. Those that return periodically have elliptical orbits with the sun as one of the foci. Those that do not usually have hyperbolic orbits with the sun as a focus.
I scientifically believe that comets are closer to the outer part of the solar system.

There are no visible comets at this time.
