Five hundred to a thousand of the known near-Earth asteroids are much bigger. They are over 1 kilometer in diameter. When large asteroids hit Earth in the past, many organisms died. At times, many species became extinct in a mass extinction. Astronomers keep looking for near-Earth asteroids. They hope to predict a possible collision early so they can to try to stop it. Q: Near-earth asteroids cross paths with earth, meaning they could collide; what are the paths called? Choices: - trajectory - curves - galaxies - orbits A:
A: orbits
