Centaurs and TNOs that reach the inner Solar System can modify the orbits of main belt asteroids, though only if their mass is of the order of 10 −9 M ☉ for single encounters or, one order less in case of multiple close encounters. However, Centaurs and TNOs are unlikely to have significantly dispersed young asteroid families in the main ...
The Grand tack hypothesis explains how in the Solar System giant planets migrated in unique way to form the Solar System belts and near circular orbit of planets around the Sun. [10] [11] [9] The Solar System's belts are one key parameters for a Solar System that can support complex life, as circular orbits are a parameter needed for the ...
A top view of asteroid group location in the inner solar system A map of planets and asteroid groups of the inner solar system. Distances from sun are to scale, object sizes are not. Various dynamical groups of asteroids have been discovered orbiting in the inner Solar System.
The Solar System remains in a relatively stable, slowly evolving state by following isolated, gravitationally bound orbits around the Sun. [28] Although the Solar System has been fairly stable for billions of years, it is technically chaotic, and may eventually be disrupted. There is a small chance that another star will pass through the Solar ...
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun. Most named objects in this list have a diameter of 500 km or more. The Sun, a spectral class G2V main-sequence star; The inner Solar System and the terrestrial planets. 2021 PH27; Mercury
Diagram showing different asteroid paths. The yellow band marks the Earth's orbit; the red line marks the asteroid's path. Outer-grazer(†): middle, bottom Crosser: right, bottom Close approach trajectory of 2004 FH in the Earth–Moon system Flyby of the near-Earth asteroid 2004 FH in March 2004.
Motion of the Solar System's barycenter relative to the Sun The center of the solar system according to the position of the planets (Jupiter, Saturn, Uranus, Neptune) If m 1 ≫ m 2 —which is true for the Sun and any planet—then the ratio r 1 / R 1 approximates to: .
Some prominent families are the Vesta, Eunomia, Koronis, Eos, and Themis family located in different (colorized) regions of the asteroid belt. An asteroid family is a population of asteroids that share similar proper orbital elements , such as semimajor axis , eccentricity , and orbital inclination .
