Well, to start off on the easy side, they are both rocks from outer-space. They both have a nucleus and they both are scientifical bodies that travel in space. The thing that comets, asteroids, and meteorites have in common is that they all travel in space and most of them all are unchanged because of their formation in the solar nebula.
A meteoroid is a small rocky or metallic body in outer space. Meteoroids can come from various sources, but the options are limited by your question. Assuming you're asking about sources that are not typical for meteoroids, the answer would be: Planets: Planets are not a source of meteoroids. Meteoroids are usually fragments of comets or asteroids. They can also be generated from collisions between larger bodies in space. Planets are much larger objects and don't typically break apart to become meteoroids. The common sources of meteoroids are comets and asteroids. When comets get close to the Sun, they release dust and gas, creating a debris trail. If Earth passes through this trail, the debris can enter our atmosphere and create meteor showers. Similarly, asteroids can collide or break apart due to various factors, leading to the creation of meteoroids.
They are all less than a kilometer in diameter.
Most of the space rocks which eventually become meteoroids formed in space about the same time as the rest of the solar system did. Probably the most common meteoroids are remnants of comets; we know that several of the annual "meteor showers" are associated with known cometary orbits. Many meteoroids were fragments broken from asteroids when they have collided. And at least a couple of meteorites which have been discovered here on Earth are known to have come from Mars! Asteroid impacts on Mars have knocked rocks and dust completely off of Mars and into orbit around the Sun, where they have impacted the Earth.
Comets are Comets and Asteroids are Asteroids
The most common magnetic element found in meteorites is iron. Another common element in meteorites is nickelwhich is also magnetic. Some meteorites also contain Cobaltwhich again is also magnetic.The most common meteorites are H-Group Chonderites which make up about 31% of all meteorites ever found. They also contain the most metal at 15 - 20%.Of this metal normally about 70% is Iron with about 29% nickel and trace amounts of cobalt along with other non magnetic metals including gold, platinum and silver.
They are all very hot.
Both meteoroid's and comets are made out of rock and burn up when getting into earths atmosphere.
Meteors (meteorites, actually) come in all sizes, from microscopic to bigger than houses. One can make artificial categories of 1) micrometeorites (very common); 2) gravel-sized meteorites (less common, but affordable) and 3) massive (seen only in museums).

Small bodies that travel through space are called asteroids, comets, or meteoroids. They can range in size from a few meters to several kilometers in diameter and are common in our solar system.
This can vary a lot between different meteors; the main classification, if I remember correctly, is between "ice meteors" that are made up mainly of ice, and "rock meteors", out of rocky materials.
scientific interest and practical importance. It is generally expected that the compositions of the asteroids that are most likely to hit Earth should reflect those of the most common meteorites. Here we report that most near-Earth asteroids (including the potentially hazardous subset) have spectral properties quantitatively similar to the class of meteorites known as LL chondrites. The prominent Flora family in the inner part of the asteroid belt shares the same spectral properties, suggesting that it is a dominant source of near-Earth asteroids. The observed similarity of near-Earth asteroids to LL chondrites is, however, surprising, as this meteorite class is relatively rare . One possible explanation is the role of a size-dependent process, such as the Yarkovsky effect, in transporting material from the main belt.

They are hitting air molecules at a high speed and breaking them apart, which produces a lot of heat.
