e. All of the above

Explanation: If material in the universe does not fully form into a star or planet, it can indeed form into a moon, asteroid, comet, or ring system.

a. Moon: Moons are natural satellites orbiting planets or asteroids. They are made from the same material as planets, just not enough to form a full planet.

b. Asteroid: Asteroids are small, rocky objects that orbit the sun. They are similar to planets but much smaller in size.

c. Comet: Comets are icy bodies in the solar system that, when passing close to the Sun, heat up and begin to outgas, displaying a visible atmosphere or coma, and sometimes also a tail.

d. Ring System: A ring system is a disc or ring orbiting an astronomical object that is composed of solid material such as dust and moonlets, and is a common component of satellite systems around giant planets.

So, all of the above options are possible formations of material in the universe that does not fully form into a star or planet.
