Query: An Improved Approach to Orbital Determination and Prediction of
  Near-Earth Asteroids: Computer Simulation, Modeling and Test Measurements   In this article, theory-based analytical methodologies of astrophysics
employed in the modern era are suitably operated alongside a test
research-grade telescope to image and determine the orbit of a near-earth
asteroid from original observations, measurements, and calculations.
Subsequently, its intrinsic orbital path has been calculated including the
chance it would likely impact Earth in the time ahead. More so specifically,
this case-study incorporates the most effective, feasible, and novel Gauss's
Method in order to maneuver the orbital plane components of a planetesimal,
further elaborating and extending our probes on a selected near-earth asteroid
(namely the 12538-1998 OH) through the observational data acquired over a six
week period. Utilizing the CCD (Charge Coupled Device) snapshots captured, we
simulate and calculate the orbit of our asteroid as outlined in quite detailed
explanations. The uncertainties and deviations from the expected values are
derived to reach a judgement whether our empirical findings are truly reliable
and representative measurements by partaking a statistical analysis based
systematic approach. Concluding the study by narrating what could have caused
such discrepancy of findings in the first place, if any, measures are put
forward that could be undertaken to improve the test-case for future
investigations. Following the calculation of orbital elements and their
uncertainties using Monte Carlo analysis, simulations were executed with
various sample celestial bodies to derive a plausible prediction regarding the
fate of Asteroid 1998 OH. Finally, the astrometric and photometric data, after
their precise verification, were officially submitted to the Minor Planet
Center: an organization hosted by the Center for Astrophysics, Harvard and
Smithsonian and funded by NASA, for keeping track of the asteroid's potential
trajectories.
