NUEVO SERVICIO DE SADEYA/INFORTECNICA Un nuevo servicio de efemérides de SADEYA/Infortécnica, desconocemos otro semejante, es la previsión de órbita de impacto de los asteroides que presentan riesgo de choque por cruce de órbitas y su limitado número de observaciones. De estar en situación de improbable impacto, las efemérides deberían ser semejantes a las calculadas. Es interesante observar el área de posible aproximación del asteroide. De encontrarse cerca, huelga decir que sería muy trascendente la astrometría de aproximación. Datos complementarios pueden obtenerse en las webs de J.P.L. Y Neodys. En 2015 hay varias previsiones de riesgo de impacto en grado 0 de la escala Torino (J.P.L.). No obstante, algunos de ellos son cuerpos potencialmente destructivos como el que nos ocupa cuyo impacto causaría graves daños globales: RIESGO DE CHOQUE DE 2004 BX159 EFEMERIDES FICTICIAS DE APROXIMACION E IMPACTO DEL ASTEROIDE 2004 BX159 2015 9 1 T= 2455865.745222 PERI= 139.8893 NODO= 157.7972 INCL= 4.64138 EXC= .6209248 q= .915395 H= 17.5 A partir de 8 observaciones 2004 1 20-23 Res med. 0".511 + Inc.T Fecha A.R.(2000)Dec.
