Warsaw Catalogue of cometary orbits: 119 near-parabolic comets
Małgorzata Królikowska
Context. The dynamical evolution of near-parabolic comets strongly depends on the starting values of the orbital elements derived from the positional observations. In addition, whe…
Near-parabolic comets observed in 2006-2010. The individualized approach to 1/a-determination and the new distribution of original and future orbits
Malgorzata Krolikowska, Piotr A. Dybczynski
Dynamics of a complete sample of 22 small perihelion distance near-parabolic comets discovered in the years 2006 - 2010 is studied. First, osculating orbits are obtained after a ca…
Note about the impact possibilities of asteroid (99942) Apophis
Malgorzata Krolikowska, Grzegorz Sitarski
The Monte Carlo method of the nominal orbit clonning was applied to the case of 99942 Apophis, the asteroid from the Aten group. Calculations based on observations from the time in…
How selection and weighting of astrometric observations influence the impact probability. Asteroid (99942) Apophis case
Malgorzata Krolikowska, Grzegorz Sitarski, Andrzej M. Soltan
The aim is to show that in case of low probability of asteroid collision with Earth, the appropriate selection and weighing of the data are crucial for the impact investigation, an…
