This new generalization of one’s method to your concentric coplanar system from N perturbing authorities provides allowed to reveal a similar qualitative pecularities of the orbit evolution of the asteroids not of the chief strip . More accurate mathematical-analytic way for study of the asteroid orbits evolution was developed considering eccentricities, tendencies, additionally the secular perturbations of one’s entire world orbits. Through this method, particularly, the posibility of qualitative changes of one’s advancement away from perihelion dispute into orbit off asteroid 2335 (JAMES) are discover . It reduses to your change out of libration regimen when you look at the flow you to and you may back over interval off ten^5-10^six ages and supply new clear example of the brand new actions in the the latest location of one’s secular resonance. These types of overall performance had been confirmed qualitatively when you look at the .

It acceptance us to rating the brand new real parameters because of it asteroid. Astrophys. Suppl. Yoshikawa Meters. Nakamura T. Services out of Close-Skip Certainly one of Asteroids I determined the orbital actions of around 4500 numbered asteroids, taking into account the outcome of your gravitational destination one of asteroids in addition to perturbation out-of 9 worlds.

The fresh new calculation is completed for around 130 decades about coming, and you may instance romantic experience you to definitely distance anywhere between several asteroids was faster than simply 0. On the 12,000 close-misses are obtained by this computation, and you will, sure enough, several occur in the main strip and around the ecliptic basic. Although not, so it calculation indicates that close-misses certainly one of asteroids take place in a very high region of the space. The product range where close-misses occur try 0. This effect means that collision away from asteroids is possible even external an element of the strip. On top of that, i examined the dependency away from close-misses toward orbital aspects (a: semimajor axis, e: eccentricity, i: inclination) and you will bulk off asteroids, therefore acquired the following results: (1) How many close-misses minimizes because a gets highest.

Then it for the reason that the outcome of period of orbital advancement. Simply because the number density off asteroids will get quicker in the event the z will get huge. This really is probably due to the fact that quick asteroids seen actually have a propensity to keeps short major axes and you may inclinations. Yuasa Yards. Round The very least Square Approximation for Household members-such as for instance Groups A family group-such as for example gang of asteroids distributed just as much as toward a circle in the newest v-you airplanes plus the latest q-p flat, where in fact the v-you plane is set of the polar coordinates with radius e (eccentricity) and you can direction omega (longitude regarding perihelion), in addition to q-p flat is set by the polar coordinates which have radius sinl (l=inclination) and you may direction Omega (longitude away from node). After that a different minimum square opportinity for circularly distributed info is developed that’s used on Amor members of the family-instance category.

By this strategy, we are able to obtain the radius r and the square coordinates (an effective, b) into the heart of network, which make d^2 = Sigma (roentgen – r(sub)j)^2 to get lessened (r(sub)j indicates the distance of each data from the center of the network).
