Objects in the Solar System

Updated June 01, 2013

Our solar system has only one star, the Sun.
However, astronomers have observed that many solar systems with two, three or more stars are numerous.
Without concurrent, the Sun has become huge, it has captured 99.86% of the total mass of dust and gas from the original nebula.
Jupiter, the largest planet in the system, has captured 71% of the remainder. The other planets are divided residue that gravitational evolution.

 

« A planet is a celestial body that is in orbit around the Sun, which has sufficient mass for its gravity to overcome the cohesive forces of the solid body and maintain hydrostatic equilibrium (spherical), which eliminated all body moving on an orbit close ».
This definition was approved August 24, 2006, at the 26th General Assembly of the IAU by a vote to freehand by 400 scientists after ten days of discussions.
