Asteroid Belts are regions in star systems that usually reside between planets. These belts exist in multiple star systems.
There is an asteroid belt in the Kirb System between Ilve's orbit and Mirn's orbit. It is a little less dense than the one around Kerbol, with a maximum inclination of 25°.
There are two small asteroid belts that reside in the Kelin System. One of them is between the orbits of Esle and Alva, and the other is between the orbits of Blalo and Elno.
Around Kernim, there is an asteroid belt between Narath and Dunem. It is much more sparse than around Kerbol or Kirb, and the maximum inclination is about 10°, making it easier to get an asteroid there than around Kerbol.
Around Kerolon, there is an asteroid belt between the orbits of Aquel and Mesmo. This one, although less dense than around Kerbol, has a higher inclination, with a maximum inclination of roughly 30°.
- The Asteroid Belts are the only regions players can pick up unidentified objects, or asteroids, and capture them, requiring much more fuel to reach an asteroid than in stock KSP.
