Rate of Δν Determination for Near Earth Asteroids

摘要: The best near-Earth asteroids (NEAs) candidates for observation are those with low ∆v as it is these that suited unmanned, manned, scientific, and commercial expeditions. majority of NEAs being discovered small dim, having a diameter less than 100 meters an absolute magnitude H ≥ 22. In approximately one week, the magnitudes so faint followup photometry, spectroscopy, astrometry no longer possible except largest telescopes. This requires follow-up observations to be done within days asteroid’s initial discovery. Given large number annually short timespan when they bright enough observations, only can selected observations. We used archival data 200 representative from Minor Planet Center (MPC) Find Orb orbit determination software Project Pluto determine speed at which orbital parameters converge on solution. Based data, after three 95% converged 10% precision.
