The correct answer is option 1, asteroids. Asteroids are small celestial bodies that are found primarily in the asteroid belt, which is a region of space located between Mars and Jupiter. They are much smaller than planets and do not have sufficient mass to form into a spherical shape like a planet. Asteroids are composed of various materials, such as rock, metal, and ice.

Option 2, comets, are also small celestial bodies, but they are characterized by a bright glowing coma and a tail when they get close to the Sun. Comets originate from the outer regions of the solar system, far beyond the asteroid belt, and some may occasionally cross the orbit of Mars or Jupiter.

Option 3, meteors, are not celestial bodies but rather phenomena that occur when smaller objects, such as asteroids or comets, enter Earth`s atmosphere and burn up upon entry. Meteors are commonly referred to as shooting stars.

Option 4, meteorites, are the remains of meteors that survive their passage through the Earth`s atmosphere and land on the Earth`s surface.
