Article about solar system.

The solar system consists of the sun and everything that orbits the sun. It is a sphere of hydrogen and helium gas held together by its own gravity. The solar system is enveloped by a huge bubble called the heliosphere. Made of charged particles generated by the sun the heliosphere shields planets and other objects from high speed.

The more distant one called the oort cloud is a spherical shell surrounding the solar system at a distance of approximately 50 000 astronomical units au more than 1 000 times the distance of pluto s orbit. Of the objects that orbit the sun directly the largest are the eight planets with the remainder being smaller objects the dwarf planets and small solar system bodies of the objects that orbit the sun indirectly the moons two are larger than the smallest planet. The solar system s several billion comets are found mainly in two distinct reservoirs. Orbiting bodies include the eight planets asteroids comets centaurs 1 trans neptunian objects and dust.

It has a 24 5 hour day polar ice caps that expand and contract with the seasons and a large array of surface features that were. However even with all these things most of the solar system is empty space. The solar system consists of the sun and everything that orbits or travels around the sun. Great pictures of everything in the solar system.

The largest and most massive object in the solar system is the sun itself. Mars is one of the most earth like worlds in the solar system. This includes the eight planets and their moons dwarf planets and countless asteroids comets and other small icy objects. This is a list of possibly gravitationally rounded objects of the solar system which are objects that have a rounded ellipsoidal shape due to their own gravity hydrostatic equilibrium their sizes range from former dwarf planets and moons to the planets and the sun this list does not include small solar system bodies but it does include a sample of possible planetary mass objects whose.
