Helin's contributions to astronomy led to advances in tracking what kind of objects?

  • Near-Earth objects

  • Distant galaxies

  • Solar flares

  • Neutron stars

Answer

Near-Earth objects (NEOs) are asteroids and comets whose orbits bring them close to Earth, posing a potential impact hazard. Helin's tireless efforts and expertise in observational astronomy greatly contributed to the discovery and characterization of numerous NEOs. His diligent observations helped track their trajectories, estimate their sizes, and assess their potential for collision with our planet.
