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.

Article about solar system. Astronomy articles on the eight planets plus the two dwarf planets pluto and eris. The solar system is enveloped by a huge bubble called the heliosphere. The latest images of our solar system and beyond. The solar system is the gravitationally bound system of the sun and the objects that orbit it either directly or indirectly.

Mars is one of the most earth like worlds in the solar system. The largest and most massive object in the solar system is the sun itself. The solar system consists of the sun and everything that orbits or travels around the sun. 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.

It is a sphere of hydrogen and helium gas held together by its own gravity. The solar system consists of the sun and everything that orbits the sun. 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. 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.

This includes the eight planets and their moons dwarf planets and countless asteroids comets and other small icy objects. Orbiting bodies include the eight planets asteroids comets centaurs 1 trans neptunian objects and dust. The solar system s several billion comets are found mainly in two distinct reservoirs. Made of charged particles generated by the sun the heliosphere shields planets and other objects from high speed.
