Here are 3 items found in space besides stars, moons, and planets:

1. Asteroids: These are rocky bodies that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter.

2. Comets: These are icy bodies that release gas and dust as they get close to the Sun, forming a characteristic tail.

3. Nebulae: These are clouds of gas and dust in space. Some are the birthplace of stars, while others are the remnants of exploded stars.
