Orbital characteristics[1] Epoch August 27, 2011 (2455800.5) Aphelion2.29608 AU (Q) Perihelion0.967688 AU (q) Semi-major axis 1.6319 AU (a) Eccentricity0.40701 Orbital period 2.0847 yr (761.4 d) Mean anomaly 201.5 Inclination0.9267 Longitudeof ascendingnode 47.505 Argumentof perihelion 204.0673 Physical characteristics Dimensions12×24 m Mass5×106 kg Sidereal rotation period 42.7 s (0.01185 h) Absolute magnitude(H) 25.7[1] Sblizheniya povtoryayutsya raz v 2 goda, bolee tesnye v 25 let. Uskorenie vrasheniya ___sootvetstvuet tyazhesti na asteroide v 100.000 bol'shem, naprimer na Cerere. Energiya vrasheniya 5 MDzh ili 1,5 kVt*ch. Mozhno zapustit' na niti kilogrammovyi ob''ekt so skorost'yu v 3 km/sek za schet vrasheniya asteroida. Zapas prochnosti kak u polmetrovoi sosul'ki. Vozmozhno vytyanutaya forma svidetel'stvuet o tekuchesti sostavlyayushego kometu l'da. Rasstoyanie do perigeliya ot orbity Zemli ne bolee 8 mln km, a mezhdu orbitami ok. 2,5 mln km. Esli na peresadku zatrachivat' pol-nedeli(ergonoma do Luny), potrebuetsya summarnyi impul's ot OZO v 20 km/sek, a pri otsutstvii nakloneniya byl by 6 km/ sek. Zato ekonomim massu zashity ot kosmicheskoi radiacii i ot sobstvennogo _reaktora - reaktor stavim za gorkoi, gorke vyrezaem rot, a rtu yazyk, poluchayutsya zuby - zhivem na meste yazyka, prikryvayas' zubami. 3 mm svinca oslablyayut izluchenie v 2 raza, 3 sm - v 1000 raz, chto uvelichivaet prodolzhitel'nost' poleta s pol-nedeli do 10 let. Massa zashity ob''ema diametrom 5 m 2.5 t, no uchityvaya' chto polovina lunnyh astronavtov umerla, zashitu sleduet uvelichit' do fonovoi smertnosti 1% god, a dlya zdorovyakov-kosmonavtov 0,5% god ili v 10 raz, chto sootvetstvuet troinoi tolshine ili 8 t svinca, a dlya diametra 10 m - 30-35 t. Yasno, chto zashita asteroidom massoi 5 tys t mogla by nam s''ekonomit' neskol'ko stupenei. Na odnu stupen' s impul'som 4 km/sek idet 2,7 krat massy. Vot stepeni 2,7: 1-2,7___2-7,3___3-20___4-55___5-150___6-400 krat. Dlya polutora tonn poleznoi nagruzki massa zashity ekvivalentna 3 stupenyam rakety. Poetomu ispol'zovat' dlya zashity kometu s takim udalennym otstoyaniem nakloneniya apolonovoi orbity nevygodno. Otstoyanie nado sokratit'_ raza v dva do mln km.
