The brightness of a comet is not determined by its distance from the sun, but rather by factors such as the size of its nucleus, how recently it has passed close to the sun, and how much dust and gas it is releasing. Therefore, the brightest comets can be found at various distances from the sun.
Superior planets (those outside Earth's orbit) appear brightest when they are at opposition, which is when they are on the opposite side of Earth from the Sun. This is when they are closest to Earth and fully illuminated by the Sun.

Those that do not survive the encounter.Generally, names given by their discoverers do not last because they, as objects, do not survive. Exceptional cases occur. Halley and Shoemaker-Levy for instance.Many, many objects in our solar system collide with the sun.So the closest are those that collide and are consumed by the sun
Both of those words refer to points in the orbit of an earth satellite ... the moon or any artificial satellite. Apogee . . . the point in the orbit where the satellite is farthest from the earth. Perigee . . . the point in the orbit where the satellite is closest to the earth.
Norway, Sweden, and Finland are the three countries in Europe that are the farthest North. If you look at a map Norway is the farthest North out of those three, but only by a small chunk of land.
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.
The current belief of virtually all astronomers is that comets were "specks" of leftover detritus from the formation of our solar system. Being the lightest of those "specks", they orbit the sun at the farthest distance - the Oort cloud, estimated to be about a light year from our sun. Note, though, that in this usage, "speck" means a ball of dirt laced with ices that's about 3 to 10 kilometers wide.
We generally believe that comets with orbits of 200 years or less, traveling in the ecliptic plane, come from the Kuiper Belt. Those comets with longer orbits, or that travel at angles to the ecliptic plane, come from the Oort Cloud.
Comets appear when they do; they don't run on a schedule. Hundreds of amateur comet hunters are watching the skies every day. In fact, several new comets have been seen this year; unfortunately, those comets have fallen into the Sun.
