Ireneusz Włodarczyk

We computed impact solutions of the potentially dangerous asteroid (443104) 2013 XK22 based on 99 optical observations from Dec. 2013 to Jul. 2016. We followed orbit of the asteroid (443104) 2013 XK22 forward in the future research for close approaches with the Earth, which can lead to possible impacts up to the year 2109. We computed non-gravitational parameter A2 = −2.04×10^-15 au d^-2 with 1σ uncertainty 1.78×10^-15 au d^-2 in the motion of the asteroid (443104) 2013 XK22. Furthermore, the possible impact corridor for the year 2101 is computed and presented. Asteroid (443104) 2013 XK22 belongs to so called possible recovery Near Earth Asteroids and can be recovered in 2028. Therefore, the ephemerides of this asteroid for observational window in 2028 are presented.
