Our solar system is a vast and fascinating place, filled with planets, moons, and other celestial bodies. One of its most famous features is the Asteroid Belt. This is a large, doughnut-shaped region of space that is located (21) __________ the orbits of the planets Mars and Jupiter. It contains the majority of our solar system's asteroids and serves as a clear boundary between the inner rocky planets and the outer gas giants.

The objects found within the belt are mainly composed of rocky material, including rock and various metals. This vast region (22) __________ of millions of individual space rocks of all different sizes, from tiny pebbles to enormous boulders. These objects are remnants from the early formation of our solar system, over 4.6 billion years ago, which were prevented from coming together to form a planet by Jupiter's strong gravity.

The items that populate this area are called asteroids, (23) __________ are ancient, rocky objects that orbit the Sun but are too small to be considered planets. The sizes of these asteroids are incredibly varied, ranging from dust-like particles to giant bodies measuring hundreds of kilometers in diameter. The asteroid Vesta, for example, is one of the largest and is about 525 kilometers wide.

Most asteroids are irregularly shaped and relatively small. However, the largest object found in the belt is Ceres. It is so large and spherical that scientists have also classified it as a dwarf planet. While there are many other large asteroids in the belt, none of them come close to the size of Ceres, which accounts for a third of the belt's total mass.

Despite how it is often shown in movies, the Asteroid Belt is mostly empty space. The distance between objects is so great that a spacecraft can fly through it without much risk. The total mass of all the asteroids combined has a surprisingly small (24) __________ on the solar system; it is estimated to be only about 4% of the mass of Earth's Moon.

Life as a 14 or 15-year-old often feels like a constant juggling act. Between school, a mountain of homework, exciting hobbies, and the all-important social life with friends, it can seem impossible to fit everything into just 24 hours.
