Channel Description
PHASTEROID TRACKER is a YT channel created to keep you up to date with the latest trajectory and news of real, last minute, present and future NEO (near earth objects), Asteroids and PHA (potentially hazardous asteroids). Source of Info: NASA. The most significant issue to remember is the inherent uncertainty in each NEO orbit. This uncertainty is related to several parameters used in the orbit determination process including the number of observations (measurements), the time spanned by those observations, the quality of the observations (e.g. radar vs optical), and the geometry of the observations. Of these parameters, the time spanned by the observations generally has the most effect on orbital uncertainty. Also note that Earth close-approach data for a given NEO can change (often by large sums) as new information become available and the orbit is updated.
