Abstract
NEO Surveys and Ground-Based Follow-up
Highlights
NEO Surveyor Mission (NEOSM) and LSST will increase by orders of magnitude the number of Near Earth Objects (NEOs) that can be targeted with small and medium aperture telescopes, increasing the observing load on current follow-up facilities
2.2 NEO discoveries benefit from coordinated operations Because asteroids’ sky positions and magnitudes quickly change as they approach and recede from Earth, there is a limited time in which follow-up observations can be made
3.1 Maintenance of the NEO catalog requires long-term monitoring More than two-thirds of Near-Earth asteroids (NEAs) are single opposition objects whose ephemeris uncertainties can be larger than the field of view of many telescopes
Summary
NEOSM and LSST will increase by orders of magnitude the number of NEOs that can be targeted with small and medium aperture telescopes, increasing the observing load on current follow-up facilities. Most NEO surveys and major follow-up projects operate multiple telescopes to maximize discoveries and to secure orbits of known catalog objects.
